How is hume's view of the mind related to that of the tibetan master milarepa's on this subject?

Both Hume and Milarepa saw self as an illusion.

Hume believes that the self as we know it is an illusion but that at times, we can catch a fleeting glimpse of the true self, which we lose sight of as we are changing constantly. To Milarepa the self is in fact an idea. He also saw self existing only as an illusion.
