So Lord Śrī Kṛṣṇa says, jarā-maraṇa-mokṣāya mām āśritya. If one has to..., has the ambition for getting out of these clutches of birth, death, old age and disease, then one, if he's intelligent enough, then, jarā-maraṇa-mokṣāya mām āśritya, under Kṛṣṇa consciousness, if one attains his life's living activities... Activities there must be. We cannot stop, so long we have got this body or we have no body. That is an activity... We are active. Every living soul is active by nature. But that activity should be coordinated, dovetailed. The activity should be in Kṛṣṇa consciousness. So jarā-maraṇa-mokṣāya mām āśritya yatanti ye. Yatanti means "one who endeavors in that way." Te brahma: "They are actually Brahman." Brahman means they are transcendental, in transcendental state. Te brahma tad viduḥ kṛtsnam: "Or they can understand what is the meaning of Brahman, or the transcendental, Transcendence." Te brahma tad viduḥ kṛtsnam adhyātmaṁ karma cākhilam: "They understand what is Brahman, and their work, their activities are also Brahman."
Now, there are two classes of transcendentalists. One class of transcendentalists, just like the impersonalists, they want to stop activities. They think like that, that when one becomes one with the Transcendence, then their activities stop. But actually, from the Bhagavad-gītā we find that te kṛtsnam adhyātmaṁ karma cākhilam. Their activities are not stopped, but the quality of the activity is changed. Brahman. The quality of activities becomes transcendental. Karma cākhilam. Akhila. Whatever he does in Kṛṣṇa consciousness, whatever he does, that becomes Brahman, or transcendental. That means free from the contamination of the three modes of material nature. Therefore, as he becomes free from the contamination of the three modes of material nature, therefore he's not going to have next body of this material nature. Next body he's not going to have material... The same example: just the, if you put iron rod into the fire, it becomes gradually the fire. The nature of fire the iron rod attains. So when it is red-hot, there is no possibility of its being the iron, but it is fire.
