Krishna consciousness is our original consciousness because every living being is part and parcel of Krishna. Krishna has many expansions. They are called personal expansions and separated expansions. We living entities are His separated expansions.
Although we are very intimately connected with Krishna, somehow or other we are now separated because of our contact with material nature. We have practically forgotten that we are part of Krishna. Actually, that is a fact. We are spoiled, just like a rich man’s son who somehow or other forgets his father, and loiters in the street as a poor man. Actually, that is not his position. He has simply forgotten.
The Krishna consciousness movement is trying to invoke in all people the original consciousness that we are part and parcel of Krishna. Why should we remain in this material world and suffer the threefold miseries? We want to revive that original consciousness. The original consciousness is Krishna consciousness.
For example, a man born of a large wealthy family should enjoy the title of his family, but unfortunately he may forget his own home and accept menial tasks. The whole Vedic literature is meant for this purpose: to revive our original consciousness. Aham brahmasmi: I am not this body, I am spirit soul.
