The conversion
Tolle has described — repeatedly and consistently — a single decisive moment in his late twenties at Cambridge: a night of suicidal despair in which the thought I cannot live with myself any longer unexpectedly opened the question who is the I that cannot live with the self?. The collapse of the felt separation that followed left him, on his account, in a state of almost continuous peace that has since become the basis of his teaching. He spent two subsequent years effectively unfunctional in conventional terms, then began teaching in the early 1990s.
What's distinctive
His work is unusual for being almost entirely undenominational. He quotes Yeshua, the Buddha and the Sufis indiscriminately, but doesn't claim a lineage or use technical Sanskrit, Pāli, or Hebrew vocabulary. The practical teaching is remarkably small: become aware of the voice in your head; recognise that you are not it; notice the present moment, this one, now. The rest of his books are extended commentary on that single instruction.
In the index
The index contains a substantial body of his short-form teaching — Q&As, talks at his retreats, and clips edited by his channel. The pieces work well as an introduction precisely because each is a small instance of the same instruction, repeated from a slightly different angle. How Do We Break the Habit of Excessive Thinking and How to Calm the Voice Inside are good starting points; the longer Conscious Manifestation live teaching is where he applies the practice to the New Thought territory.
