Attaining spiritual insight has a long tradition of erotic metaphor. It's a bit like having sex for the first time, there is a sense of initiation, of irreversible change, of becoming mature, "putting behind childish things"... This passage implies that there are many more such moments down the line. A repeating cycle of mystical fruitions, maybe?
At least, that is what I get from it. But Baha'is tend to be politely distanced when I want to talk about the mystical vibe of their scriptures.
Do you enjoy Sufi poetry,
@RJM? There are plenty of parallels in style and symbolism with the Baha'i corpus.
