Astrology is useful.  It answers a lot of questions about why we do what we do, because the blueprint we set out with at birth is available to us.  We can consult it for clarification when we are stumped about what to do next.  We make up our own minds; but it’s there as a reference, should we choose to look.
That blueprint is a natal horoscope, or birth chart.  It looks like this:
As you can see, it looks like a wheel divided into 12 sectors.  Each sector, called a house, represents an area of one’s life.  The 1st House represents our modus operandi; the 2nd, our values (including money); the 3rd, communication and siblings; the 4th, home and foundations.  The 5th House indicates self-expression; the 6th, health, routines, and service; the 7th, relationships.  The 8th House deals with transformation: birth, death, legacies, lawsuits.  The 9th House shows travel and higher education; the 10th House, career; the 11th House, friends and societies; and the 12th House reveals our spiritual path. 

Within each of the Houses dwell planets: the Sun (our basic personality); the Moon (our inner nature); Mercury (how we think and communicate); Venus (what and whom we love); Mars (our desires, temper, and work-style); Jupiter (our personal philosophy); Saturn (our discipline, structure, and fears); Uranus (the mad genius within each of us); Neptune (our compassion and spiritual selves); and Pluto (our power and passion). 

By studying this graphic representation of the moment of our birth, we can learn how to enhance our strengths and downplay our vulnerabilities.

Astrology is useful.  It is, in its way, a map to the treasure hidden within.
