Lord Caitanya explained to Sanatana Gosvami the real constitutional position of the individual. He said directly that each and every individual soul is eternally a servitor of Krsna. Jivera svarupa hayakrsnera nitya-dasa: [Cc. Madhya 20.108] every individual soul is eternally a servitor. When one is fixed in the understanding that he is part and parcel of the Supreme Soul and that his eternal position is to serve in association with the Supreme Lord, he becomes self-realized. This position of rightly understanding oneself cuts the knot of material attraction (hrdaya-granthi-bhedanam). Due to false ego, or false identification of oneself with the body and the material world, one is entrapped by maya, but as soon as one understands that he is qualitatively the same substance as the Supreme Lord because he belongs to the same category of spirit soul, and that his perpetual position is to serve, one attains atma-darsanam and hrdaya-granthi-bhedanam, self-realization. When one can cut the knot of attachment to the material world, his understanding is called knowledge. Atma-darsanam means to see oneself by knowledge; therefore, when one is freed from the false ego by the cultivation of real knowledge, he sees himself, and that is the ultimate necessity of human life. The soul is thus isolated from the entanglement of the twenty-four categories of material nature. Pursuit of the systematic philosophic process called Sankhya is called knowledge and self-revelation.
