Krishna continues His granular breakdown of human psychology. Having analyzed knowledge, action, and the worker, He now turns to two critical internal faculties: understanding/intelligence (buddher) and determination/fortitude (dhṛteś). He promises Arjuna (Dhananjaya) to explain their threefold division (tri-vidhaṁ) based on the modes of nature (guṇatas), completely and in full detail (aśeṣeṇa pṛthaktvena).
