There is a crucial point here that I would like to draw your attention to: people often use the truth of no-self to rationalize all sorts of strange and maladaptive behaviors because they misunderstand it as justifying a nihilistic perspective: “It's all illusion anyway,” or, “I don't even ultimately or truly exist so why bother?” It absolutely is not all merely illusion, and since we do exist conventionally, and conventional causality functions, “bothering” is a really good idea. The illusions are in how we misconceive and misperceive phenomena versus how they actually exist.
