There are so many societies where the members seriously discuss Vedanta philosophy while smoking and drinking and enjoying a sensual life. It will not help if one only has knowledge theoretically. This knowledge must be demonstrated.

Practical Knowledge

Theoretical knowledge alone insufficient

"A person is said to be established in self-realization and is called a yogi (or mystic) when he is fully satisfied by virtue of acquired knowledge and realization. Such a person is situated in transcendence and is self-controlled. He sees everything—whether it be pebbles, stones or gold—as the same." (Bhagavad-gita 6.8)

Jñana means theoretical knowledge, and vijñana refers to practical knowledge. for instance, a science student has to study theoretical scientific conceptions as well as applied science. Theoretical knowledge alone will not help. One has to be able to also apply this knowledge. Similarly, in yoga one should have not only theoretical knowledge but practical knowledge. Simply understanding "I am not this body" and at the same time acting in a nonsensical way will not help. There are so many societies where the members seriously discuss Vedanta philosophy while smoking and drinking and enjoying a sensual life. It will not help if one only has knowledge theoretically. This knowledge must be demonstrated. One who truly understands "I am not this body" will actually reduce his bodily necessities to a minimum. When one increases the demands of the body while thinking "I am not this body," then of what use is that knowledge? A person can only be satisfied when there is jñana and vijñana side by aide.

When a person is situated on the practical level of spiritual realization, it should be understood he is actually situated in yoga. It is not that one should continue to attend yoga classes and yet remain the same throughout his life; there must be practical realization. And what is the sign of that practical realization? The mind will be calm and quiet and no longer agitated by the attraction of the material world. Thus self-controlled, one is not attracted by the material glitter, and he sees everything—pebbles, stones or gold—as the same. In the material civilization, so much paraphernalia is produced just to satisfy the senses. These things are produced under the banner of material advancement. He who is situated in yoga sees such paraphernalia as just so much rubbish in the street. Moreover,

"A person is said to be still further advanced when he regards all—the honest well-wisher, friends and enemies, the envious, the pious, the sinner and those who are indifferent and impartial—with an equal mind." (Bg. 6.9)

There are different kinds of friends. There is suhrit, who is by nature a well-wisher and is always desiring one's welfare. Mitra refers to an ordinary friend, and udasina is one who is neutral. In this material world someone may be my well-wisher, friend or neither friend nor enemy but neutral. Someone else may serve as a mediator between me and my enemies, and in this verse he is called madhya-stha. One may also see someone as pious and another as sinful according to his own calculations. But when he is situated in transcendence, all of these—friends, enemies or whatever—cease to exist. When one becomes actually learned, he does not see any enemy or any friend because in actuality "no one is my enemy, no one is my friend, no one is my father, no one is my mother, etc." We are all simply living entities playing on a stage in the dress of father, mother, children, friend, enemy, sinner and saint, etc. It is like a great drama with so many characters playing their parts. However, on the stage a person may be an enemy or whatever, but off the stage all the actors are friends.

Similarly, with these bodies we are playing on the stage of material nature, and we attach so many designations to one another. I may be thinking, "This is my son," but in actuality I cannot beget any son. It is not possible. At the utmost I can only beget a body. It is not within any man's power to beget a living entity. Merely by sexual intercourse a living entity cannot be begotten. The living entity must be placed in the emulsification of secretions. This is the verdict of Srimad-Bhagavatam. Thus all the multifarious relationships between bodies are just so much stage play. One who is actually realized and has actually attained yoga no longer sees these bodily distinctions.
