A person acting in Krsna consciousness (or, in other words, in the service of Krsna) with his body, mind, intelligence and words is a liberated person even within the material world, although he may be engaged in many so-called material activities. He has no false ego, nor does he believe that he is this material body, nor that he possesses the body. He knows that he is not this body and that this body does not belong to him. He himself belongs to Krsna, and the body too belongs to Krsna. When he applies everything produced of the body, mind, intelligence, words, life, wealth, etc.—whatever he may have within his possession—to Krsna's service, he is at once dovetailed with Krsna. He is one with Krsna and is devoid of the false ego that leads one to believe that he is the body, etc. This is the perfect stage of Krsna consciousness.
