Buddha

Satipatthana Sutta

There is this one way for the purification of beings, for the overcoming of sorrows and griefs, for the going down of sufferings and miseries, for winning the right path, for realizing nibbana, that is to say, the four applications of mindfulness. The Buddha

The Enlightened Body, by John Aske

Only by familiarizing ourselves with all the elements, allowing these things to pass into our awareness untrammelled, and then out again — to allow them their changing nature — only in this way can we learn to live with them, accept them and be free of them. What we do not accept, what we love and hate, we are bound to.

Love, by Ajahn Sumedho

And it is a mystical one. But then we have to deal with our emotional natures which are usually not developed or evolved.
