It seems to me that a mountain is an image of the soul as it lifts itself up in contemplation. For in the same manner as the mountain towers above the valleys and lowlands at its foot, so does the soul of the one who prays mount into the higher regions up to God like an eagle taking wing.
Ecstasy results from the wisdom of emptiness, of seeing the impermanent, insubstantial nature of all phenomena, where there is no clinging, no attachment, and no fear. In this experience, we become one with the unfolding process of life. This oneness is quite subtle, because it is the oneness of becoming zero.
