Mukti is consciousness transformed from bodily identification to eternal service of Krishna.Listen — Srila Prabhupada Uvaca
Śrīmad-Bhāgavatam 5.5.2 — April 13, 1975, Hyderabad 750413SB-HYDERABAD [77:01 Minutes] SB-05.05.02_750413SB-HYDERABAD Prabhupāda: ...mahat-sevāṁ dvāram āhur vimuktes tamo-dvāraṁ yoṣitāṁ saṅgi-saṅgam [SB 5.5.2] For two days we have explained mahat-sevāṁ dvāram āhur vimukteḥ. People have forgotten at the present moment what is the meaning of mukti. They do not know practically. Mukti means the..., to get out of the clutches of the stringent material laws.
That is called mukti. We are at the present moment conditioned, so many conditions. So mukti means to live without condition. That is called mukti.
The mukti definition is given in the Śrīmad-Bhāgavatam: muktir sva-rūpeṇa vyavasthitiḥ. Muktir hitvānyathā rūpaṁ sva-rūpeṇa vyavasthitiḥ [SB 2.10.6]. This is called mukti. We are not in the svarūpa.
Svarūpa means spiritual form. That is called svarūpa. At the present moment, our material conditional body, that is not svarūpa. Last night I tried to explain, svarūpa means sac-cit-ānanda-rūpa.
That is svarūpa—eternal, blissful life of knowledge. This is not svarūpa. This body is not eternal, neither it is blissful. It is full of miseries and without any knowledge.
So this is not svarūpa. Svarūpa means eternal life, blissful life, and full of knowledge. That is called svarūpa. So we do not know that we are now living conditional life, virupa, which is not my svarūpa.
This is the science that svarūpa can be perceived, can be realized. That is described in the Śrīmad Bhagavad-gītā: brahma-bhūta. Brahma-bhūta, spiritual realization, that is also not svarūpa. That is the beginning of self-realization. brahma-bhūtaḥ prasannātmā na śocati na kāṅkṣati samaḥ sarveṣu bhūteṣu mad-bhaktiṁ labhate parām [Bg. 18.54] That is svarūpa.
