Aham Brahmasmi: (Sanskrit: अहं ब्रह्मास्मि aham brahmāsmi) “I am Brahma” I am Spirit Soul.
Brahma means: spiritual, and aham-brahmasmi means: I am a spirit soul. I am not this body.”The symptoms of the self-realized person are given herein. The first symptom is that he is not disillusioned by the false identification of the body with his true self. He knows perfectly well that he is not this material body, but spirit soul, the fragmentary portion of the Supreme Personality of Godhead.” (Bg 5.20, Purport by Srila Prabhupada)
“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.”
