We Are Not Void, We Are Spirit Souls - Prabhupada 0781
680309 - Lecture SB 07.06.03-4 - San Francisco
If you want to meditate, meditation means to attempt to understand oneself, "What I am." That is real meditation. Meditation does not mean that . . . of course, this voidness, meditation in voidness, is another negative attempt that This body is nothing. But actually, I am not void; I am spirit soul. And because I have no information of the spirit soul, therefore I simply try to think of the negative side of this bodily existence. That is called voidness.
Simply negative . . . now, I am not this body. I am not this body. I am not this body, that's all right. But that is not perfect self-realization.
