In this era of technology, it is becoming increasingly difficult to lead peaceful lives. Men are becoming the targets of various types of mental ailments. In countries on the frontline of civilisation like America and England, people have lost the delight of natural sleep at night. They experience only artificial sleep induced by the tablets they swallow. As a consequence of these and many other drugs taken to ward off other ills, they suffer more and more from diseases of the heart and blood pressure. In the end, they render themselves unhealthy wrecks. Such lives are highly artificial. People are sunk in fear and anxiety; mentally on one side and physically on the other, they have no rest. Drugs, tablets, capsules and pills are produced in millions but the general health has not improved. Besides, new varieties of illness have emerged and are developing fast. A few intelligent westerners have realised that their only refuge is Yoga; they have confirmed their conclusion by means of experiments; they have taken to Yoga with increasing faith.

The Vedas are the oldest literary creations of man. Now the word 'literature' is used to connote writings scribbled while eager to find something to spend the time hanging on hand. They have no inner worth or significance; they destroy the traits of good character in the reader and implant bad attitudes and habits; they do not adhere to the path of Truth. But, Literature is a term that cannot be applied to writings or poems that reel off tales that are false. It should not emerge from the egotistic fancies of the individual.

The Vedas are the soul that sustains the spiritual life of Bharath; they are the breath that keeps the people alive. They possess a divine power, amazing in its effects. They are charged with the vibrations of mantras, which can be experienced by those who go through the process scientifically. They can impart also the strength derivable through symbols and formulae of Tantric nature. 'Tantra' means 'the means and methods of utilising the mantras for one's own good'. Man has physical and material power only. His Karma becomes holy and sacred when the mechanics (yantra) of life are ruled by Mantra and Tantra. The technique of this Sadhana is in the Karma Kanda of the Vedas. The ancient sages became aware of this and have preserved it for mankind in the Four Vedas.
