The debate is over. Krishna speaks with authority now: 'Hear my definitive view on this matter, O best of the Bharatas.' He declares that tyaga is of three types. No ambiguity, no hedging. This is the teacher drawing a line and saying — pay attention.
There is warmth in the way Krishna addresses Arjuna here. He calls him Bharatasattama (noblest of the Bharata clan) and Purushavyaghra (tiger among men). These are not hollow titles. Krishna is reminding Arjuna of who he is — a warrior worthy of receiving the highest teaching.
The three types of tyaga — sattvic, rajasic, and tamasic — will be spelled out in the shlokas that follow. This verse is the turning point from debate to declaration.
