As Sam Harris puts it, the illusion of free will is itself an illusion.
When we observe our thoughts, we see that they float up and pop up into our consciousness. We are not creating our thoughts. In fact, we cannot know what our next thought and emotion might be.
The present is a deep mystery.
This is what the great masters of non-duality were struggling to convey: that there is no central controller organising itself and the world. Stuff happens, and “we” lay a layer over it and make ourselves the protagonists of our narratives.
A truly liberating insight.
