Then the idea that has existed in Christianity is also a riddle to solve that we may find out the truth of life. It is the idea of the Trinity. What keeps the soul in perplexity is the threefold aspect of manifestation. As long as the soul remains in this puzzle, it cannot arrive at the knowledge of the One. These three aspects are: the Seer, Sight, and the Seen; the Knower, Knowledge, and the Known. Plainly explained, I would say: these are three aspects of life. One aspect is the person who sees; the other aspect is the sight, or the eyes, by the help of which he sees; and the third aspect is that which he sees.
