Anyway, I was wondering if the dream reflects that you are growing in knowledge, considering the angle of etheric libraries, astrology as connected to psychic talent, and astrology as a stepping stone to higher knowledge. That is the most positive. The danger, as from the continuation of the excerpt, are books of little value. That said, now as in the past there are good astrologers, if they have much knowledge and good talents.
In a more general interpretation, it may have to do with seeing the unseen in a situation, finding a way, connecting to what one should do, which astrology can also be. Since you were shown books from a long time ago by a custodian of knowledge, is there help from the other side? Is something being revealed within?
