The worship of the Great Mystery was silent, solitary, free from all self-seeking. It was silent because all speech is of necessity feeble and imperfect ... it was solitary, because the people believed that the Great Spirit is nearer to us in solitude, and that no one was authorized to come between an individual and the Creator. Among us, all were conscious of their divinity.
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.
