The doctors are daily operating, heart operation, and so many finer, finer surgical operation, but they cannot find out where is the soul. But soul is there. That we can perceive. When the soul goes away from the body, we can understand, "Now the soul has gone; the body is dead." So you can perceive; you cannot see. It is not understandable by speculating your gross senses. You cannot . . . if you want to see what is mind, what is intelligence, what is soul, what is Supersoul, that is not possible to see by your these blunt eyes, conditional eyes. Everyone is very proud of his senses. Somebody says, "Can you show me God?" But have you got the power to see God first of all? So these things are not very intelligent questions and answer. You have to practice according to the direction of the śāstra.
Just like here is Bhagavad-gītā. You follow the direction, you will understand what is God, what you are, what is this world, what is our relation between ourself, what is our condition, how we can get out of this miserable condition. Everything you will find. In the beginning a small child cannot understand what is mathematic, but if he studies mathematic science, he one day becomes a very big mathematician, the same child. Similarly, this spiritual science, every one of you can become spiritually advanced provided you study the science. That is Kṛṣṇa consciousness movement. It is not a bluff sentiment.
