BG 18.16

Therefore one who thinks himself the only doer, not considering the five factors, is certainly not very intelligent and cannot see things as they are.

18.16. But this being the case, whosoever views himself as the sole agent (cause of actions) due to his imperfect intellect - he, the defective-minded one, does not view [things rightly].

18.16 But the fool who supposes, because of his immature judgment, that it is his own Self alone that acts, he perverts the truth and does not see rightly.

18.16 See Comment under 18.17

18.16 In fact, the agency of the individual self is subject to the consent of Supreme Self; such being the case, if the 'individual self regards Itself as the agent,' It is of wicked or perverse mind. For, It does not perceive the agent as It really is, since It possesses an 'uncultivated understanding,' namely, an understanding which does not reveal the real state of affairs.

18.16 Tatra is used for connecting with the topic under discussion. Tatra evam sati, this being the case, when actions are thus accomplished by the five causes mentioned above;-this portion has to be connected with 'perverted intellect' by way of causality [Actions are done by the body etc., but since a person thinks that the Self is the agent, therefore he is said to have a perverted intellect.]-yah, tu, anyone, an unenlightened person, who; pasyati, perceives; kevalam, the absolute, pure; atmanam, Self; as the kartaram, agent-thinking, 'I myself am the agent of the actions being done by them', as a conseence of imagining the Self as identified with them; why?-akrta-buddhitvat, owing to the imperfection of his intellect, owing to his intellect not having been refined by the instructions of Vedanta and the teachers, and by reasoning-. Even the person who, believing in the Self as distinct from the body etc., looks upon the distinct [Ast. omits anyam (distinct).-Tr.], absolute Self as the agent, he, too, is surely of imperfect intellect. Hence, owing to his having an imperfect intellect, sah, that man; na, does not; pasyati, perceive (properly) either the truth about the Self or about actions. This is the meaning. Therefore he is a durmatih, man of perverted intellect, in the sense that his intellect is contemptible, perverse, corrupted, and the cause of repeatedly undergoing births and deaths. He does not perceive even while seeing-like the man suffering from Timira seeing many moons, or like one thinking the moon to be moving when (actually) the clouds are moving, or like the one seated on some conveyance (e.g. palanin), thinking oneself to be moving when others (the bearers) are moving. Who, again, is the man of right intellect who perceives correctly? This is being answered:

18.16 Such being the case, he who sees only the self as the agent on account of the uncultivated understanding - he, of wicked mind, does not see at all.

18.16 This being the case, anyone, who, owing to the imperfection of his intellect, perceives the absolute Self as the agent, that man does not perceive (properly), and has a perverted intellect.
