All meditation aims to bring the person, mind and body to silence, stillness and simplicity of spirit by means of an inner "object of attention". The act of attention is the inner sacrifice, and the work of paying attention is the school of letting go. The utter simplicity of such a way to joy and peace makes one laugh. God seduces us by simplicity.
It is not enough to seek and care; to pay lip service to all manner of ideals. Real witness is what counts. It is something to do with leaps in the dark. Recognizing that Truth is hidden. But transformation towards truth is something else. It is practice and diligence.
