Query: OM Ramana

Ramana is the nectar of advaita/non-duality teachers. In this compilation of the Maharshi's meetings with disciples, author David Godman introduces the topic in a couple of pages before printing the talks. Others have summed up Ramana's teaching with something like: "There is no separated doer". If you want more, try this book.
