Sri Abhinav Gupta
18.26-28 Muktasangah etc. upto Tamasa ucyate. He who does not make speech of egoism : He who does not claim ‘I am the agent’ i.e., he who is different from the one who claims so by natural inclination, or claims as such with an intention that ‘I should do so’, or claims so in an efficient manner. This nini (suffix employed in anahamvadi) does not prohibit for a Yogin, the speech ‘I do’ under the influence of the cover of the mundane life. Who is overpowered by joy and grief : i.e., at the time of success and failure [respectively]. Wickedness : cruelty.
18.28 ‘Ayukta’ is the doer who is unalified for acts enjoined by the Sastras; the meaning is that he is engaged in perverse acts; who is ‘unrefined’, means one uninstructed; who is ‘stubborn’, means one who is not disposed to act; who is ‘depraved’ means one who has the taste for black magic etc; who is dishonest is one who is treacherous; who is ‘indolent’ is one who is not inclined to carry out actions undertaken; who is ‘despondent’ is one given to excessive despondency; and one who is ‘dilatory’, is a person who, while engaged in black magic, etc., pays malevolent attention to produce long-standing evil to others - such a doer is declared to be Tamasika.
Thus, has been told the threefold division in terms of the Gunas of the knowledge about the work that ought to be performed, and about the agent of work. Now, Sri Krsna describe s the threefold division of Buddhi and Dhrti (fortitude) on the basis of Gunas. These faculties give the determinate knowledge of all realities in existence and of all ends of human life (Purusarthas).
