Open, attentive listening can be a form of contemplative prayer. It can be that widest, most open form of being present and attentive, in trust that God is present with us, in expectancy that the Spirit will move in the hearts of those present and that we may be changed inwardly for the good or guided to be part of the upwelling of Life in a particular situation.
Mysticism is about being-with-being: being-with-being in silence, in experience, in awe, in connection making, in non-dualism, and also about being with suffering beings, with the victims of self-hate and oppression.
A prophet is a mystic in action.
