It is simple to discover who your Moon Angel is all you need is access to the appropriate Emphemeris for your year of Birth or use one of the many internet website who can calculate your birth details on your behalf.

Chaos Astrology is an exploration into the application of chaos theory to astrology. For astrology, as for chaos theory, destiny (outcome) is a combination of fate (determinism) and free will (randomness). As the website and natal reports point out, the birthchart is a set of instructions, imperatives, or 'life path', if you like; what one must do in order to fulfill a cosmic purpose. Any chart, or part of the chart, can be read in this light. In the case of horary, it can be seen as the cosmic path of least of resistance, the status quo, what will tend to happen given minimal human interference. We do not lose our free will, but rather we can use the information given in the chart to make better informed decisions. http://www.chaosastrology.net/astroform/ephemeris.cfm
