Prabhupāda: You have got book? Śrutakīrti: Yes. [break]
Devotee: Oṁ namo bhagavate vāsudevāya. Oṁ namo bhagavate vāsudevāya. [devotees chant responsively] [leads chanting of synonyms] [break]
Devotee: śrī bhagavān uvāca yogasya lakṣaṇaṁ vakṣye sabījasya nṛpātmaje mano yenaiva vidhinā prasannaṁ yāti sat-patham [SB 3.28.1] [02:04] "The Personality of Godhead said: My dear mother, O daughter of the King, now I shall explain to you the system of yoga, the object of which is to concentrate the mind. By practicing this system one can become joyful and progressively advance towards the path of the Absolute Truth." Prabhupāda: śrī bhagavān uvāca yogasya lakṣaṇaṁ vakṣye sabījasya nṛpātmaje mano yenaiva vidhinā prasannaṁ yāti sat-patham [SB 3.28.1] So this word yoga is very popular in the Western countries. Practically everyone knows the word at least, yoga. And many so-called yogīs come here, and I do not want to discuss.
But yoga is a very nice process by which you can make your mind very peaceful, and then you can make progress towards spiritual life, sat-pathe. Our..., there are two ways. One is called sat-patha, and one is called asat-patha. Asat-patha means..., asat means which will not exist.
That is called asat. And sat means which will exist. The spirit will exist; matter will be finished. Now you have got this body.
You have got this body. This body will be finished, everyone knows. But the spirit soul within the body, that will not finish. Na hanyate hanyamāne śarīre [Bg. 2.20].
