Teachings Values through Ramayana




The Ramayana is one of the greatest epics of Hindu Mythology. Written by the Hindu sage Valmiki, the Ramayana is not just a story, but also an educational medium used by the ancient sages to espouse the importance of doing your dharma (duty) in relationships. The Ramayana depicts characters that we should aspire to be like, such as the ideal father, ideal son, ideal brother, ideal leader, ideal wife, etc. 

Learn how you can use one of the greatest gems of Hindu Mythology, namely the Ramayana to teach your family moral values and ethics with the following suggestions.


Sibling Relationships
If your child has any siblings, focus on the love the brothers had for each other. Why did Lakshman, who was used to all the worldly luxuries due to a prince, decide to give all of that up voluntarily to live with his elder brother for 14 years of hardship in a forest? Because he loved his brother and could not bear the thought of having to live 14 years without him.

You can also teach your child the importance of standing up for his siblings with the example of Surpanakha. When Surpanakha was insulted by Lakshman, her brothers Khaara and Dooshan rushed to avenge her not caring of the fact that it could lead to their death. When Rama and Lakshmana did indeed vanquish her brothers, Surpanakha sought her other brother Ravana's aid, setting the wheels for the grand battle between Rama and Ravan, good and evil, into motion. 

In today's materialistic world where disputes between siblings are commonplace, stories like these need to be extolled and repeated time and again. Parents need to encourage their children to not only spend time with their siblings, but also stand up for each other and be there for each other when required. Such deep affection can be cultivated only when parents encourage such growth, and keep emphasizing the importance of love amongst siblings.

Differentiating between Right and Wrong
You can teach your child to choose right over wrong even when wrong may feel more right by giving him the example of Bharat, who was awarded the honour of ruling the mighty kingdom of Ayodhya. Bharat could have just accepted the throne and the absolute power and luxury that came with it but his sense of right and wrong would not permit him to do what most others would greedily do. Instead, upon learning that his mother Kaikeyi had unjustly managed to get Rama banished from Ayodhya, he immediately went into the forest to look for Rama and offer him his rightful position as ruler of Ayodhya. So great was his devotion to his brother and so strong was his desire to be fair and just, that when Rama refused to return to Ayodhya before completing his 14 years in exile, Bharat placed Rama's footwear on the throne and ruled Ayodhya in the name of Rama – as Rama’s emissary until he returned to regain his rightful position. 

This teaches your child that even if something is extremely desirable, he should only accept it if is attained in a just manner without hurting or affecting anyone else in an unfair and unjust manner.

The Value of a Promise
Dashrath had granted Kaikeyi two boons when she had saved his life on the battlefield. The day before Dashrath was to retire and crown his eldest son Rama as king, Kaikeyi demanded that Dashrath grant her the boons she desired as promised. Her first desire was that Rama should be exiled to the forest for fourteen years, and the second, that her son, Bharat, be crowned King in his stead. Dashrath was naturally heartbroken at the prospect of having to send his son into exile for fourteen years, but for this noble hearted clan, honouring one’s word is the highest duty. Even when Dashrath began to falter at the prospect of actually following through on his promises due to his love for his first born and pleaded with Rama not to leave, Rama reminded his father of the value of a promise given and left Ayodhya to keep his father’s word. When Bharat begged Rama to return to Ayodhya, Rama once again reminded Bharat that he could not and would not dishonour his father by breaking the promise he had made to Kaikeyi.

If Rama, a prince who had been brought up in the lap of luxury and who stood to gain a position of absolute power and luxury if he disregarded his father’s promise, willingly chose to live a life of exile and hardship for 14 years in a forest, what does it teach our children? It teaches them not to tarnish the value of their promise for small and unimportant things like eating their veggies or finishing their homework and so on.

Love and Respect for Parents
Rama's insistence on keeping the promise made by his father also shows the deep love and devotion that he had for his parents. He willingly chose to spend 14 years in exile in a forest to protect his father’s much respected honour. Such was the regard he paid to his father. Dashrath too loved his child so deeply that when Rama left for the forest, Dashrath could not bear the thought of being away from his son for 14 years and breathed his last.
This demonstrates the love and respect Rama had for his parents. He listened to every command his parents made, he honoured their promises and ensured that no one could accuse them of being unfair. He did not go against his parents’ wishes even though being passed over for the throne was unfair to the firstborn son of the ruler of a mighty kingdom. He obeyed his parents and is immortalised for doing so. It also showcases the love parents have for their children. Hopefully, the fact that Dashrath dies pining for his son will make them aware of the attachment you have for them and will make them more respectful of and more devoted to you.

Beware of Bad Counsel
Kaikeyi was fundamentally a good natured woman, but was convinced to send Rama into exile and insist on her son Bharat being crowned king by the venomous counsel of her maid servant whom she consider loyal and wise. Manthara’s vicious scheming not only poisoned Kaikeyi’s mind into demanding those two appalling boons, but also ruined her life. She lost her beloved husband to heartbreak and her son Bharat, for whom she asked for those very boons, chastised her for dreadful behaviour.

This is a very important lesson for your children. It teaches them to stay on guard against vicious counsel. It teaches to be vigilant in order to avoid being scammed. It teaches them to be firm of mind and not let their minds get swayed easily by people. It teaches them to question their behaviour and think of the consequences of their actions before making any big or small decisions.

Protecting the Weak
Jatayu, an aged demigod in the form of a vulture, witnessed Ravana kidnapping Sita and taking her forcefully to Lanka. Disregarding his old age, Jatayu tried to save Sita by fighting Ravana valiantly but failed. Rama and Lakshman came across him where he was lying breathing his last. Jatayu informed Rama about Sita’s whereabouts and Ravana’s plans before breathing his last. Moved to tears by the gallantry and courage of the aged Jatayu, Rama gave the bird its last rites as though the bird was his father.

This teaches your child that he must always stand up for the weak. If his friends begin bullying a younger child, your child’s moral code will not allow him to just stand by as a meek spectator. The fact that Jatayu was so old and still tried to take on the powerful Ravana single-handedly, teaches your child to be courageous and be unafraid to take on any challenge that comes his way and accomplish it to the best of his ability. 

Therefore, retell the Ramayan to your children not just for its piety, but also because the magnum opus teaches your children to have strong morals and live a life of righteousness. The Ramayana will enrich their lives and help you mould your children to be the leaders of tomorrow with strong cultural and traditional influences.

Inertia Base by Easyflex



The inertia bases are specifically designed and engineered to receive poured concrete which can be supplied empty, pre‐filled with concrete or pre‐filled with Pumps fitted. It is by adding this mass and by lowering equipment centre of gravity it is installed under that enables the inertia base to provide a stable support. This is particularly important for equipment which exhibits high out‐of balance forces and are top‐heavy such as pumps. The concrete base enables a reduction in motion from pump start up and minimises the effect of unequal load distribution.

Inertia bases are not only manufactured to suit the equipment for which it’s designed to support but can also be sized to suit site conditions. This is particularly advantageous in tight restrictive areas such as building services plant rooms.

All Bases are supplied with Anti‐Vibration Mounts designed to support the combined load of Pump, Concrete Base and Water and retain a 50% overcapacity.

When installing rubber bellows to a pump that is supported by inertia base the rubber bellows should be supplied with tie bars. Tied units are designed to stop the bellows from elongating and prevent the pressure thrust being transmitted on to the pumps and associated pipework. Easyflex rubber bellows are supplied with fully threaded tie rods whose primary function is to maintain the supplied length of the rubber bellows under pressure while permitting only lateral deflection.

International Yoga Day - 21st June

Origin : The idea of International Day of Yoga was first proposed by the current Prime Minister of India, Mr. Narendra Modi during his speech at UNGA (united nations general assembly) , on 27 September 2014 . 

He stated :
Yogistic is a valuable gift of India's ancient tradition. It embodies unity of mind and body; thought and action; restraint and fulfillment; harmony. It is not about exercise but to discover the sense of stillness with oneself, the world and the nature. By changing lifestyles and creating consciousness, it can help in well- being. Let us work towards adopting an INTERNATIONAL YOGA DAY

The origins of yoga are shrouded in mystery and mythology while some historians find many clues in the practices of Himalayan Shamans as still be seen in Tibet and Nepal. The Lord Shiva is considered as the father of Ancient Yoga while some of historians claim that Patanjali is the father of modern Yoga. 

By the 5th century BC yoga was becoming well known and begun to appear in Vedic scripture. The word Yoga is a Sanskrit word and it comes from the root Yuja which basically means to bind to align to hold.

WHY 21st JUNE AS YOGA DAY ?
When proposing 21 June as the date of yoga, it is said that the date was the longest day of the year in the northern hemisphere, having special significance in many parts if the world .From the perspective of yoga, the summer solstice mark transition to Dakshninayna. The first full moon after summer solstice is known as Guru Poornima . Shiva , the first yogi is said to have begun imparting the knowledge of yoga to the rest of mankind on this day and became the first guru (Adi Guru).

Bad Isolation - Some Common Problems Seen in the Field - Easyflex


In most commercial and industrial buildings, you will find some type of vibration isolation on the mechanical equipment. If the products have been specified and installed correctly, they should be providing a significant reduction in the force transmitted to the structure, relative to the force that would be transmitted if the equipment was “bolted down.” In our experience, there is a good chance that the isolation is not working properly.
Most problems with vibration isolation can be easily avoided. There are three areas where problems frequently occur:
1)     Improper design, selection & specification
2)     Incorrect installation
3)     Inadequate maintenance
Improper Design, Selection & Specification
The 2015 ASHRAE Handbook on HVAC Applications (Chapter 48 on Noise and Vibration Control) is an excellent source of design information for vibration isolation. We at Easyflex have developed installation guidelines for most commonly used mechanical equipment that should allow the engineer to specify the correct isolation for most types of equipment. Please contact us if you need assistance for both installation guidelines, drawings or tender specifications. Problems arise however, either because the proper sources are not consulted or the information on the drawings is incomplete.
One of most common errors is overloading or under-sizing of the isolator. For springs, it should be obvious when this has occurred, but it is surprising how often it is seen in the field. The figure below shows two examples of fully compressed springs. A well-designed spring will have an additional “travel to solid” of 1.5 times the rated deflection, so the springs shown below are loaded to at least 1.5 times their rated capacity. They should be replaced by stiffer springs providing the specified deflection.

Overloaded spring isolators – pump base (left), spring hanger (right).
For resilient isolators such as rubber pads, overloading may not be so obvious. Special care must be taken with this type of isolator, especially when a concentrated load is applied directly to a pad or sheet of material.
Housed spring isolators are commonly used as OEM equipment, but if possible they should be avoided, due to the potential for binding, corrosion, and debris/liquid collection. The figure below shows a housed two-spring isolator that appears to be working properly, but closer inspection reveals several problems related to the potential for binding, or “short circuiting”. First, due to a slight misalignment, the housing and the nested shell are in contact. Although a piece of resilient material prevents metal-to-metal contact, this condition is less than ideal (notice that the pad on one side is missing). Second, the bolt between the two springs appears extremely close to contacting the springs, which is also bad. Third, the potential for debris getting into the housing and interfering with the isolation is obvious.  On rooftop installation, we have seen ice build-up and bind in the isolator, which prevents it from moving freely.

 Housed spring isolators should be avoided
For some reason, housed isolators are frequently included as part of the original equipment on HVAC equipment such as fans and chillers. When this occurs and it is impractical to replace them, extra care must be taken in the installation and maintenance. Another shortcoming of some housed isolators is that they do not include a neoprene “acoustical” cup under the springs. This feature helps attenuate high frequency vibration that may travel through the spring.
Incorrect Installation
By far the most prevalent installation “misstep” is to place an anchor or other rigid metal part in parallel with the isolator. This occurs frequently since the installer wants to hold the equipment in place. An example is shown for a small air compressor below. In this example, if the bolt is placed in an oversized hole, a neoprene washer is used, and the nut is only finger tight, then this arrangement is acceptable. There should be no metal-metal contact if vibration isolation is to be effective. The bolt then only provides restraint against excessive motion, not normal vibratory motion.


 Another curious example is shown below. The pumps are isolated with springs under pump bases, but the pipe stands at the end of the pumps are supported directly on the slab below. In this case a larger base should have been used to allow the stand to be supported by the base. Essentially the housekeeping pad shown is too small for the pump size.

A bolt or other rigid metal part installed in parallel with the isolator can render it ineffective
Misalignment is a common problem for both spring mounts and hangers. As shown below, misalignment can create contact resulting in “short circuiting” of the isolation. The remedy for this lies with careful quality control in the field. It is the responsibility of the contractor to ensure that the springs are installed with concentric loading. For hangers, this involves drilling overhead holes, which must be located accurately relative the pipe being supported. Isolator alignment requirements should be stated clearly in the project specifications.
A second type of problem that occurs with hangers is essentially the opposite of the overloading problem discussed above. The figure below shows a spring hanger that is obviously not supporting any load. The clevis hanger below the spring isolator is simply too big. In this case, either a smaller clevis hanger should have been used or the available one modified.


 Spring hanger problems – misalignment (left), oversized clevis hanger (right)
Flexible connectors are a critical element in the isolation of equipment with connected piping. One frequently encountered problem with braided stainless steel hose is installation in a vertical orientation, when the vibratory motion is also in this direction. The figure below shows an example of incorrect installation. Since the braided stainless steel is relatively stiff along its length, it is not an effective isolator for motion in this direction. The flexible hose should have been installed horizontally, perpendicular to the plane of motion. It is easy to see why this is sometimes not done, since it requires extra space which may not be available if this arrangement was not anticipated. If a vertical installation is required, an elastomeric connector should be considered.
In this photo, note that the concrete inertia base has been correctly sized to support the pump stand.


Braided steel connectors should be installed perpendicular to the direction of vibratory motion (not as shown)
Inadequate Maintenance
All too often, vibration isolation is installed and forgotten. Mechanical rooms in older buildings can be virtual museums of ancient, neglected isolation hardware. In many cases the hardware is no longer providing effective isolation. See the photo of a badly corroded mount below. In spite of its bad condition, it may continue to support the equipment for a long time, and probably does not need to be replaced unless a vibration problem is occurring. In other cases, the isolation should be restored by replacing or repairing the hardware.
Another case of a housed spring isolator in bad condition is shown below. It also appears that the height-saving bracket was poorly designed and has experienced excessive distortion.

A corroded leveling mount (left), a housed spring isolator in bad shape (right)
Oftentimes building maintenance personnel will make creative retrofits to vibration isolation, such as in the situation shown below. Pieces of 2x4s have been used to shore up a fan on which the hangers were not working properly, and the fan is now supported on the duct below. When this type of situation is encountered, it should be corrected as soon as possible. In some cases, modifications to the isolation can create a safety hazard, especially in high seismic areas.

 A creative retrofit to vibration isolation
Like the equipment itself, the vibration isolation has a finite lifespan. It is often the case that when the isolation is in bad shape, the equipment is also old. Hence, a major replacement or upgrade of the isolation on existing equipment may not be a good investment. However, any new equipment should be properly fitted with the most up-to-date vibration isolation.
The Bottom Line
Proper design, installation, and maintenance are the keys to providing long term, effective vibration isolation of mechanical equipment. In building projects, vibration isolation can be a significant part of the mechanical equipment budget.  Because of this, it is incumbent upon engineers, suppliers, and contractors to provide the most effective isolation possible within the project budget. The project specifications should be clear with regard to the vibration isolation requirements. Once in place, the isolation should be well maintained. In this way, value to the building owner will be maximized and occupants will receive the benefits of low vibration.
