Sound –A Form of Energy
Sound is a form of energy carried by waves of vibrating particles . These waves are called Sound Waves. They can travel through solids, liquids and gases, but they cannot travel through vacuum as there are no particles to vibrate. For this reason, sound cannot travel out in space.
Sound Waves are longitudinal waves. It means that the particles vibrate in the same direction as the waves travels. Waves frequency is measured in hertz(Hz).Sound waves with frequencies between about 20 and 20,000 hertz can be heard by the human ear and are commonly described as sound. Sound waves below this range re known as infrasound and above it are ultrasound. High sounds such as bird song. Have high-frequency waves, whereas low sounds, such as the rumble made by the engine of a heavy truck, have low-frequency waves. The sound of an aircraft landing measures about 120 dB. Aircraft make such loud sounds that ground crew wear ear protectors to avoid hearing damage.
Loud sounds are waves with a large amplitude. Soft sounds are waves with a small amplitude . as a sound travels farther away from its source, the amplitude becomes smaller and so the sound becomes quieter. The loudness of sound is measured in decibels(dB). The blue whale is the loudest animal in the world. It makes sounds up to 188dB. The sound of falling leaves measures 10 dB.
Speed of Sound: Sound Waves travel at different speeds in different substance. They travel more quickly in solids than in liquids and more quickly in liquids than in gases. The speed of sound waves as they travel through dry air at 0 degree Celsius is 331 meters per second. This speed increases if the air temperature goes up, and decreases if the temperature of the air goes down.
A speed that is faster than the speed of sound in the same conditions is known as a Supersonic Sound. One that is slower is a Subsonic Speed.
Echoes: Echoes are sound waves that have reflected off a surface and are heard shortly after the original sound. Echoes can be used to find the position of objects. When animals such as bats and dolphins use echoes. It is called echo location. They use it to find their way around or to locate prey.
Sonar is the name given to the method used by ships to measure thee depts. Of sea water or to detect underwater objects such as shipwrecks or shoals of fish. The echoes are detected by equipment on board the ship. hoes are also used in Ultrasound Scanning to see inside the body-for example to check on the growth of an unborn baby inside its mother Bone, muscles , and fat all reflect ultrasonic waves differently. A computer uses this information to make a picture.

We lie the loudest when we lie to ourselves.
Chronic Fatigue Syndrome
People with chronic fatigues syndrome are not just tired; there fatigue is debilitating, keeping them away from work and play for months. It is accompanied by lot of symptoms that come and go, including muscle pain, sore throat, tender lymph nodes, headaches and impaired memory. Still doctors are not sure as to what causes chronic fatigues syndrome, but it affect large number of people . one theory suggests that a virus, stress or trauma jump-starts the immune system which remains activate instead of gearing down as it should. As a results , immune factors, (some of which cause fatigues) may remain in high concentration n the blood.
Chronic fatigues syndrome has many similarities to (gibromyalglia) reare disorder of the soft tissues. Some people say these two are the same . People with fibromyalgia also feel tired, but their main complaint is muscles pain.
A Diagnosis of chronic fatigues syndrome is made only after a medical checkup has ruled out other problems . symptoms are usually relieved with pain medications and antidepressants. Moderate exercise also is helpful.
Integrity
I am not bound to win, but I am bound to be true.
I am not bound to succeed, but I am bound to live up to the light I have.
I must stand with anybody that stands right, stand with him while he is right, and part with him when he goes wrong.
True Courage is Cool and Calm
Courage consists , not in blindly overlooking danger, but in seeing and conquering it .
True courage is cool and calm, The bravest of men have the last of a brutal, and in the very time of danger are found the most serene and free.
Courage is considered as an essential of character
Conscience is the root of all true courage, if a man would be brave let him obey his conscience.
Impure Thought
Impure thoughts awaken impure feelings, lead to impure expressions, and beget impure actions and these affect both body and mind and to the ruin of all that is noble and pure in character .
Life must be lived forwards
Life is like playing a violin solo in public and learning the instrument as on plays it.
The business of life is to go forward.
Life can only be understood backwards but it must be lived forwards.
The truth is that happiness is the most powerful of tonics in life.
Quote from The essence of Gita
According the scholars in Europen and America, Indian religion or Indian philosophy speaks of only detachment. It says “Don’t care for anything in this world. Renounce, renounce.” That is way, these scholars feel, a sort of melancholy or depressing tendency is found in the Hindu race, a kind of indifference or lack of enthusiasm for doing anything Hindus have the attitude.” What’s the point in doing anything in this evanescent life?” This has led to laziness and inertia.
How far these ideas are true becomes clear as soon as we study the Gita. I am not referring only Sir Krishna’s repeated instruction to not stop working. We see that Krishna himself demonstrates at every moment of his life intense activity in the midst of intense ret. He does every kind of work, but within him there is extraordinary serenity. It is this state that Krishna refers to as “detachment”
I drive joy
There was a doctor in Benaras who spent 5 minutes in the morning and evening for mediation on God. Knowing this, his colleagues and friends laughed at him. One day they argued that he was wasting ten precious minutes on something, which he had been misled into believing. The doctor replied, “Well, if God does not exist, I agree that I am wasting ten minutes a day. But, if He exists? I am afraid you are wasting your entire lifetime. I prefer to waste ten minutes rather than a lifetime. Why should you grudge me the 10 minutes joy that I derive from? I am not robbing you of your joy; why should you rob me of mine. He asked. The critics were silenced. –Baba- Chinna Katha

What I Learnt From Life

Monday 22–May- 2010
What I Learnt From Life
Oscar Wilde, master of sparkling prose and ever lasting witty poems once said that Experience is the name we give to our mistakes. The man who boasts of having the richest experience might be the one who has made the largest number of mistakes.
There are times when a small crisis appears terrible but then by the same time next day, it has lost its dimension and a little later, it has faded into memory. How much would it help us to take life’s problems with equanimity, if only we could remember the words of and old song “What would it matter, a ten years from now?’
I have learnt that human life is a difficult riddle to solve. Good people suffer, the evil ones thrive. A long time ago, in Israel, and old man sat writing a book into which he poured out al his wisdom. In lines of memorable prose he wrote: “The race is to the swift, nor the battle to the strong”.
What does this mean? As I understand it, it means that things happen to each one of us, which have no relationship to our birth or intelligence or any other qualities. So we see the not infrequent instances of very bright young men under employed or sometimes unemployed, the not-so-bright ones in positions of power and prestige. I have therefore learnt that in the interests of our own health we should not compare ourselves with those who are better off than us but count our own blessings and be grateful to God.
Think of this famous Arabian proverb which can restore sanity to the troubled world. “I had no shoes and I murmured until I met a man who had no feet.”
Speak To Everyone Kindly Lovingly, Gently
Confucius, the great Chinese philosopher was in deathbed. His near and dear ones surrounded his bed. Weakly, he whispered. “Can you see what is in my mouth?’
The old philosopher has lost al his teeth. So they replied, “We only seethe tongue”.
After a while , Confucius asked them “What is in your mouth?”
“We have both our tongues and teeth”, they answered.
The wise old man then told them, “When man is born, he is born only with a tongue. The teeth come in gradually. They are harder and stronger than the tongue! But as man grows older, his hard, strong teeth drop off gradually. Only the tongue, soft and gentle , lasts till the end”.
The dying philosopher paused for breath and told. This is my last message to you, my dear ones that which is gentle lasts. Therefore, always speak to everyone kindly, lovingly, gently!”

Irritable Bowel Syndrome? IBS?
Irritable Bowel Syndrome (IBS) is the most common chronic health disorder in America, Canada, the UK, Australia, and New Zealand, affecting more people than asthma, diabetes, and depression combined. Irritable Bowel Syndrome is a physical - not psychological - disorder that affects mainly the bowel, which is also called the large intestine. The bowel is the part of the digestive system that makes and stores stool. IBS is characterized by its symptoms: lower abdominal pain or discomfort, diarrhea, constipation (or alternating diarrhea/constipation), gas, bloating, and nausea. There is no cure for Irritable Bowel Syndrome, but there are many very effective ways of controlling and even eliminating IBS symptoms.

Irritable Bowel Syndrome is not a disease. It's a functional disorder, which means that the bowel simply does not work as it should. Irritable Bowel Syndrome is characterized as a brain-gut dysfunction.

Symptoms of Irritable Bowel Syndrome - What Are IBS Symptoms?
It's important to verify that your symptoms match those of IBS before you accept this diagnosis. As noted, Irritable Bowel Syndrome is characterized by its symptoms: continuous or recurrent lower abdominal pain or cramping (from mild to excruciating) in association with altered bowel motility (diarrhea, constipation, or both). Attacks may strike suddenly at any time of day or night, and may occasionally - though not typically - wake you from a sound sleep. Gas and bloating are common, but vomiting isn't, though it can occur due to nausea from the pain. Upper GI symptoms are not a typical part of the syndrome. For women, attacks are often associated with menstruation. Passing blood, running a fever, swollen extremities, and joint pain are not symptoms of IBS, and point to other disorders. IBS is diagnosed in part by the use of the official diagnostic criteria known as the Rome Guidelines.

What Symptoms and Diseases Need to Be Ruled Out For an IBS Diagnosis?
In essence, the diagnosis of IBS is a process of exclusion. There is no medical test available that will be positive for IBS; instead, your doctor will test you for all other illnesses that can mimic IBS symptoms, and if those tests are negative, and if your symptoms fit the Rome Guidelines for Diagnosis, you'll then be diagnosed with IBS. In particular, it's important that the following diseases are excluded before you accept a diagnosis of IBS:
Quote from True Religion Always Help
We are aware that in some countries , by some governments, experiments are being made on purely materialistic and atheistic lines to bring about ‘progress’. The first thing to remember about these experiments is that these are experiments . the time is not yet ripe to assess their full effectiveness in regard to all-round human progress. The second thing about these experiments is though officially religion is eschewed in governmental endeavors, no power on earth can take away religion-which is a matter of heart and soul-from the common man. In other words, purely materialistic or atheistic endeavors for progress do not result in progress at all, and if they do it will be found that at some level of national life, overtly or covertly, religion or the essential inspiration of religion, get mixed into the stream. Therefore-even if a government may not encourage the pursuit of, or even so much as acknowledge the existence of religion-to the reckoning of the total effect of national endeavor, factually one cannot leave out of consideration the contributory effect or religion.
Some others feel religion is not practical they want religion to prove its credentials by successfully implementing their projects. They ask, what good is religion if it does not help them in their business? At a certain stage of development some persons do not know how to put any more intelligent questions. This question, however, need not be sneered at. And to us another question arises; what exactly is our business when we take the whole of life at all levels into consideration?
