Bhagavad Gita · Sankhya YogaChapter 2, Shloka 32 (2.32)

"Yadṛcchayā" — unsought. Arjuna did not start this war; the Pandavas had made efforts for peace. This war came "of its own accord" — through circumstances. Shankaracharya: aprārthitatayā — without being asked for. That is, Krishna is speaking here not of seeking out war but of accepting the duty that has come before you.

"Svarga-dvāram apāvṛtam" — an open door to heaven. In traditional kshatriya dharma, a hero's death in a righteous war was held to lead to heaven. Krishna makes use of this common belief.

Is this the lure of a "reward"? On the surface it seems Krishna is tempting Arjuna with heaven. But look at the context: in 2.42–2.46 Krishna himself will criticise the heaven-centred desire for rewards, and in 2.47 he will ask Arjuna to give up desire for the fruit. So many commentators take the arguments of 2.31–2.37 as an answer to Arjuna's worldly doubts — not the final teaching (Shankara: laukika nyāya).
