4.19 Budhah, the wise, the knowers of Brahman; ahuh, call; tam, him; panditam, learned, in the real sense; yasya, whose, of the one who perceives as stated above; samarambhah, actions-whatever are undertaken; are sarve, all; kama-sankalpa-varjitah, devoid of desires and the thoughts which are their (desires') causes (see 2.62)-i.e., (those actions) are performed as mere movements, without any selfish purpose: if they are performed by one (already) engaged in actions, then they are for preventing people from going astray, and if they are done by one who has withdrawn from actions, then they are merely for the maintenance of the body-; and jnanagni-dagdha-karmanam, whose actions have been burnt away by the fire of wisdom. Finding inaction etc. in action etc. is jnana, wisdom; that itself is agnih, fire. He whose actions, karma, described as good and bad, have been dagdhani, burnt away by that fire of wisdom, is jnana-agni-dagdha-karma. However, one who is a perceiver of 'inaction' etc. [Perceiver of inaction etc.: He who knows the truth about action and inaction as explained before.-Tr.] is free from actions owing to the very fact of his seeing 'inaction' etc. He is a monk, who acts merely for the purpose of maintaining the body. Being so, he does not engage in actions although he might have done so before the dawn of discrimination. He again who, having been engaged in actions under the influence of past tendencies, later on becomes endowed with the fullest Self-knowledge, he surely renounces (all) [Ast. adds this word sarva, all.-Tr.] actions along with their accessories as he does nnot find any purpose in activity. For some reason, if it becomes impossible to renounce actions and he, for the sake of preventing people from going astray, even remains engaged as before in actions-without attachment to those actions and their results because of the absence of any selfish purpose-, still he surely does nothing at all! His actions verily become 'inaction' because of having been burnt away by the fire of wisdom. By way of pointing out this idea, the Lord says:

4.19 The wise call him learned whose actions are all devoid of desires and their thougts, [Kama-sankalpa is variously translated as 'desires and purposes', 'plans and desires for results', 'hankering for desires', etc. But Sankarcarya shows sankalpa as the cause of kama. -Tr.] and whose actions have been burnt away by the fire of wisdom.
