Emotions are the result of the interaction of our sense of self with the world, both the world as it is, and the world as we imagine it to be.
There is a deep truth here somewhere, that I do not have the time to contemplate. I will say that I have always felt an intuitive connection with Tantra; and I was thinking about Zen this morning: it feels to me like the effort to interact with the world via mind, without the mind. It is an attempt at pure experience, without emotions. It has always felt hollow and superficial to me, a putative cure for intellectualism which actually feeds it.
But what do I know?
