So Prahlāda Mahārāja suggests the remedy, how to become free from anxieties. He says hitvātma-ghātaṁ gṛham andha-kūpaṁ. Ātma ghāṭam. Ātma means the soul, and ghāṭam means killing. Hitvātmā-ghāṭam gṛham andha-kūpaṁ. Andha-kūpa means blind well. Blind well... I do not know whether you have got experience. In India there are several old wells on the paddy fields and they are covered with grass. Nobody can understand that there is a well underneath this, underneath this grass. And if by mistake one comes there, he falls down, say hundred feet down. And it is covered with grass. Even if he cries, "Please save me, save me," who is going to save him? Sometimes cow and animals and men fall down in that way. If he's fortunate enough, somebody comes and rescues. Otherwise, generally, there is no rescue. Who is going to know that there is a man or there is an animal? So hitvātmā-ghāṭam andha-kūpaṁ. This material world is just like that blind well. If somebody falls down in it, it is very difficult to get out of it. Therefore it is ātmā-ghāṭam. Ātma-ghāṭam means killing the soul. How we are killing the soul? We forget that "I am spirit soul." Therefore almost every one of us is forgetful that "I am spirit soul. I am identifying with this body." And Prahlāda Mahārāja says, because we have identified with this body, therefore we are always anxious, full of anxieties. And that is the fact.
Therefore the whole process of knowledge is... I think some of my student, she is present here. She asked me, "What is knowledge?" The knowledge is that "I am not this body." This is knowledge. Knowledge does not mean that how you can manufacture nuclear weapon. That is not knowledge. That is illusion. Real knowledge is to know the simple fact that "I am not this body." That's all. But that knowledge is very rare. And to acquire that knowledge, there are so many systems. That system is called self-realization. There is yoga system, there is jñāna system, jñāna-yoga, dhyāna-yoga, karma-yoga. There are so many yoga systems simply to come to the platform of this knowledge that "I am not this body." And as soon as one comes to this platform that "I am not this body," then what happens to him? Brahma-bhūtaḥ, self-realization. And what is that self-realization? What is the symptom? How I can understand that one is self-realized? Prasannātmā. He's jolly. (laughter) The... So long we do not come to that platform of knowledge, we are full of anxieties. And as soon as we come to the platform of knowledge that "I am not this body," the immediate symptom is joyfulness, prasannātmā.
