It is significant that the Latin word "templum" originally meant a vast space, open on all sides, from which one could survey the whole surrounding landscape as far as the horizon. This is what is meant to CONTEMPLATE: to "set one's sights on" Heaven from the temple that defines the field of vision... The temple is the place, the organ of vision.
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.
