These techniques of tantra, bring you to a particular point in life, where you can experience what you are. In the feverish run of life, with its passions, excitements and amidst the deceptive behaviour of the mind, a great tragedy has taken place in the life of man; he knows everything but himself. Man thinks he knows everything, geography, astronomy or technology, but he does not know who he is. He does not know his own nature or his name, but still he craves for happiness. Is it not funny that you do not know yourself?
Look at a madman in the street. If you ask him his name, he will say different names to different people. If you ask him where he lives, he will say one thing to one person and something else to another, because he is mad and does not know about himself; and that has also been the tragedy with most of us. Yet, if you can transcend the limitations of mind and body, even for a moment, you can have a glimpse of this knowledge. This is the purpose of yoga and tantra. Through these simple, graduated practices, you can go to the root of eternal life. You begin with hatha yoga, then go on to raja yoga. Finally, you must come to tantra. After tantra, you know who you are.
