Even after telling Arjuna to do as he wishes, Krishna's profound love as a friend compels Him to speak once more. He tells Arjuna to hear again (bhūyaḥ śṛṇu me) His supreme, absolute word (paramaṁ vacaḥ), which is the most deeply confidential and secret knowledge of all (sarva-guhyatamaṁ). Why is Krishna revealing the ultimate secret? Simply because Arjuna is very, very dear to Him (iṣṭo 'si me dṛḍham iti), and He only wishes for Arjuna's absolute benefit (vakṣyāmi te hitam).
