Madhudviṣa: "In the Viṣṇu Purāṇa also this truth has been established. It is stated there that Viṣṇu and His abodes all have self-illuminated spiritual existence. The words existent and nonexistent refer only to spirit and matter. That is the version of all seers of truth. This is the beginning of the instruction by the Lord to the living entities who are bewildered by the influence of ignorance. Removal of this ignorance means reestablishment of the eternal relationship between the worshiper and the worshipable and the consequent understanding of the difference between part-and-parcel living entities and the Supreme Personality of Godhead. One can understand the nature of the Supreme by thorough study of oneself, the difference between oneself and the Supreme being understood as the relationship between the part and the whole. In the Vedānta-sūtra as well as in the Śrīmad-Bhāgavatam, the Supreme has been accepted as the origin of all emanations. Such emanations are experienced by superior and inferior natural sequences. The living entity belongs to the superior nature, as will be revealed in the Seventh Chapter. Although there is no difference between the energy and the energetic, the energetic is accepted as supreme and the energy, or nature, is accepted as the subordinate. The relationship of the living entities therefore is always to be subordinate to the Supreme Lord, as with master and the servant or the teacher and the taught. Such clear knowledge is impossible to grasp under the spell of ignorance. To drive away such ignorance, the Lord teaches the Bhagavad-gītā for enlightenment of all beings for all time." Seventeen: "That which pervades the body is indestructible. No one is able to destroy the imperishable soul."
Prabhupāda: Now, "pervades the body," that is consciousness. The soul is very small, but... Just like you take one grain of, what is called, poison? Snake poison? Arsenic? Poison called? What is called? Yes, venom poison.
