Devotee: What is... What is real meditation?
Prabhupāda: Real meditation is to find out the Supersoul within the core of the heart. That is real meditation. God is situated in everyone's heart, so the yogīs, they try to find out Supersoul within the heart. That is real yogī. Dhyānāvasthita-tad-gatena manasā paśyanti yaṁ yoginam (SB 12.13.1). This is real yogī, trying to contact the Supersoul. They are searching after the God in His all-pervading feature. But, ah, some of them, they want to become one. That is asuric. One with God, that is asuric. Because they are being defeated by God, so therefore they want to become God to stop this defeat. That is asuric. Therefore they will never be able to be, but they are trying for it.
Devotee(2): It is the highest blasphemy.
Devotee(2): It is the highest blasphemy, isn't it? If one says, "I am God."
Prabhupāda: No, highest ignorance, highest rascaldom. (laughter) Yes. How one can become God? If one can become God, that means the such-and-such, he was God. Then how he has become dog? That is another rascaldom, ambition.
Devotee(2): A devotee is only supposed to want service, and sometimes he very much wants to be liberated to be finished with all this difficulty, isn't it?
Devotee(2): Is it very contaminating?
Prabhupāda: Not contaminating, not in the highest stage. That is not contaminating. If the devotee wants liberation, then they're in the lower stage. Actually, a devotee, he is already liberated. Why he shall aspire after liberation?
Devotee(2): Pure devotee's liberated.
Prabhupāda: Therefore when he's purified, he's already liberated. There is no question of his aspiring after liberation. He's already liberated. Sa guṇān samatītyaitān brahma-bhūyāya kalpate (BG 14.26).
Devotee(3): If the devotee's purified, he's convinced that if he becomes purified he will be free.
Prabhupāda: Yes. The whole devotional process is purificatory process. The more he is purified, he becomes high-class devotee. But the process is the path of liberation. Just like mango. The green mango, this green mango will be ripe mango. The same mango. You cannot say that the ripe mango is different from the green mango. It is a process. By the process the same green mango becomes yellow; then it is perfect.
