The psychic experience and mystical phenomena are certainly very interesting and reveal the unsuspected powers which lie latent within the human soul. He should not, however, preoccupy himself too much with them, as they are only the by-products of the spiritual path. Much more important is the experience of a mental stillness and emotional purification and superphysical consciousness. The ennoblement of character and the discipline of thought are really more valuable in the end than psychic phenomena.
