Wettimuny’s The Buddha’s Teaching and the Ambiguity of Existence [PDF] builds a bridge between the most important thoughts and thinkers of the east and west: the existentialists in the west, and the Buddha in the east. It completes the task begun by the Existentialists, to bring western humanity into maturity after a particularly difficult adolescence.
This book is like a manual for an arcane and esoteric, but essential piece of software: you don’t even know you need it until you come to the point in your work when it is required—and then you need it very badly indeed.
This is an unapologetically difficult book; maybe a few dozen people in the whole world are capable of understanding it completely. But for the westerner coming from a background of existential philosophy who is seriously trying to implement the teaching of the Buddha, it will be nothing less than a lifesaver.

Bhante, thank you for providing this helpful resource. I am slowly working through the material. I noticed that YouTube will not let me view the video for section 5.2, I get an error that the content is private. Is this on purpose or are the privileges just set wrong?
