Ezequiel 47

Ezequiel 47:3

After these things, the intellect comes to behold that which in Ezekiel the Prophet is indicated by the apparition of the torrent, which depicts the figure of the three stages of soul that draw nigh to things divine, and beyond the third there is no passage. The beginning of all these things is a good purpose directed toward God, the manifold labours of stillness, and the straightforwardness that is born of prolonged separation from the world. — ASCETICAL HOMILIES 18
