Brunetto Latini

What does this passing through the ocean signify? Man can approach the planets while with the last portion of his soul's being he still remains within the physical. But when he thus goes inward through the gates of the senses, eventually he must take with him the very last relics of his soul, so that he may consciously enter the condition in which he is normally only in sleep. Ordinarily, when he is with the planets, he still remains in the body with a portion, as it were, with a fragment of his soul. But when he draws even this last out of the body, it seems to him as though he were floating through the universal ocean of spiritual being.
