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.
The field of space and time is invisible, but in that space and time is the conscious awareness of the mind of the universe. Within it are mystical experience an high loving. The cosmos is being created in its entirety every eco-second. We are working with God in a process of coevolution.
