Can astrology answer every question?

One of the most common misconceptions is that an astrologer should answer questions that we do not have the answer to ourselves. Modern astrology does not predict future, because something like that does not exist when there is consciousness. Astrology helps us understand Cosmic cycles. If an inanimate object can have an “unpredictable destiny”, why would a person be predictable!? Can any literary work be completely interpreted in such a way that the meaning of metaphors and literary symbols does not allow for a different interpretation?
