From Allegory to Anagoge: The Question of Symbolic Perception in a Literal World
http://www.skyscript.co.uk/allegory.html

Angela Voss discusses how it is possible to divine:

Yet at the heart of astrological practice and teaching lies a process that defies the strivings of the mind and is itself profoundly mysterious: how to 'see' symbolically. How do we help clients to glimpse the underlying meaning of their concrete life-dilemmas, and how do we teach students to begin to move from fact-accumulation to an awareness of a different kind of knowledge, one which arises at the interface of their soul with the world?
The article is quite general and its ideas not limited to astrology. I found it helpful.
