Service is one of the two main levers of evolution: one is meditation, the other is service. Service, of whatever kind, gradually distances you from yourself. As your service grows, expands outwards from yourself, you do not lose touch with yourself but you become less and less concerned with your own ego, your personality expression. Service is the impulse of the soul, the carying out of soul purpose.
As long as the soul is not still there can be no vision, but when stillness has brought us into the presence of God, then another sort of silence, much more absolute, intervenes: the silence of a soul that is not only still and recollected but which is overawed in an act of worship by God's presence.
