Chapter 15 asks whether anything has svabhāva, a self-nature that makes it what it is from its own side. Lama Marut works through general categories and particulars, the fire that is hot but not hot from its own side, and why something that is produced can’t also have an unchanging essence. The conclusion: things exist like a dream (so row, row, row your boat) and the nature of things is that they have no fixed nature (which is the good news of our Buddha Nature or infinite potential). And if you want more wisdom: be nicer.
