SB 3.28.37

This stage of life is explained by Rūpa Gosvami in his Bhakti-rasamrta-sindhu, that a person whose mind is completely dovetailed with the desire of the Supreme Personality of Godhead and is cent per cent engaged in the service of the Lord, he forgets his material demands of the body. And in another place Sri Narottama dasa Thakura, he also explains that "One who has forgotten the demands of this material body, where is their conditional life?" That means as soon as one is free from the material demands of the body, he is actually free. And that stage is obtained being situated in one's actual constitutional position. This mukti or liberation means to be situated in the identical position of the individual soul. The individual soul is eternally the servitor of the Supreme Soul. So as soon as he is situated in that service, transcendental loving service, without being impelled by the concoction of the mind, just according to the direction of the Supreme Lord or His bona fide representative, he is considered to be a liberated person. Just like one in a business forgets how many times he has gotten up and how many times he has seated on his chair, he forgets. Similarly the..., whether he is sitting or…, or he is standing, that has no calculation. Similarly, a liberated person engaged in the transcendental service of the Lord has no perception of his material body. So: brahma-bhūyaya sa kalpate. The Bhagavad-gita [Bg 14.26] also says like that, that "One who is cent-per cent engaged in the unalloyed devotional service of Lord Krsna, he is in the Brahman stage of life; he is no more in the material stage." Here the word used: yato 'dhyagamat svarūpam (y-a-t-o-a-d-h-y-a g-a-m-a-t s-w-a-r-u-p-a-m) This is the realization of one's self.

Now one may argue that how is he in self although he is in the material body? That is explained that svarūpam means, a liberated soul means that he has no activities in relationship with the body. A devotee does not act in relationship with the body, and the conditioned soul acts on the basis of relationship with the body. A devotee acts for Krsna, and a conditioned soul acts for his relatives in relationship with this material body. Therefore, the activity shows his real identity. If one acts on account of Krsna as Arjuna fought on account of Krsna. On his bodily platform he did not like to fight because he was on the bodily plat..., that is not his svarūpam, his real identity. But in the transcendental platform when he dovetailed himself with the desire of the Supreme Lord, that is called svarūpam. So this svarūpam means self-realization. This is self-realization.
