The source of loving service for others is a heart that is aware, sensitive and conscious of one's own feelings and the feelings of others -- this is the goal of meditation.
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.
