BG 16.22

The man who has escaped these three gates of hell, O son of Kuntī, performs acts conducive to self-realization and thus gradually attains the supreme destination.

16.22. O son of Kunti ! A man, who has deserted these three gates of darkness, does what is good for his Self and thery reaches the highest goal.

16.22 These are the gates which lead to darkness; if a man avoid them he will ensure his own welfare, and in the end will attain his liberation.

16.21-22 Trividham etc. Etaih etc. Because the traid of desire etc., constitute the gate to the hell, therefore one should avoid that. What has been stated should not be neglected on the assumption that it is [based on] the human word. On the other hand, there is the authority of the eternal scripture on this subject. This is said [here] –

16.22 One who has been 'released from these three' - from desire, wrath and greed which constitute the gates of darkness causing erroneous knowledge of Myself -, he works for the good of the self. Gaining knowledge of Myself, he endevaours to be inclined towards Me. From there, he attains the supreme goal, which is Myself. Sri Krsna now teaches that the main cause of this Kind of degeneration is lack of reverence for the Sastras:

16.22 O son of Kunti, narah, a person; who is vimuktah, free; etaih, from these; tribhih, three; tamo-dvaraih, doors to darkness, i.e., passion etc. which are doors to the darkness of hell consisting of sorrow and delusion; freed from three three which are such, acarati, strives for;-for what?-sreyah, the good; atmanah, of the soul: darred by which (doors) he could not strive earlier, and on the dispelling of which he strives. Tatah, thery, as a result of that striving; yati, he attains; the param, suprme; gatim, Goal, i.e. Liberation, as well. [Not only does he attain Liberation by renouncing the demoniacal alities, but he also secures happiness in this world.] The scripture is instrumental in this complete renunciation of the demoniacal alities and striving for what is good. Both can be undertaken on the authority of the scriptures, not otherwise. Hence,

16.22 One who has been released from these threefold gates of darkness, O Arjuna, works for the good of the self. Hence he reaches the supreme state.

16.22 O son of Kunti, a person who is free from these three doors to darkness strives for the good of the soul. Thery he attains the highest Goal.
