Translation
Hear my conclusions as to that relinquishment, O best of the Bharatas; since relinquishment, O tiger of men, has been explained as threefold.

Explanation
Krishna signals that a definitive ruling is coming, and previews the method: tyaga itself is not a single, unified thing but comes in three flavors. This threefold move is the chapter’s core technique, and it will be applied not just to relinquishment but, in turn, to knowledge, action, the actor, the intellect, resolve, and happiness — the guna-typology introduced for divine and demoniac natures in chapter 16 and applied to faith, food, and sacrifice in chapter 17 is revealed here as the master key to the Gita’s entire ethical vocabulary.
