The Chinese Zodiac

The Chinese Zodiac is a symbolic cycle of twelve animal signs, with each sign reflecting qualities traditionally associated with these animals. The Chinese New Year (which occurs in January or February), marks the transition from one sign to the next and people born in particular years are believed to exhibit some of the corresponding zodiac characteristics.

The Four Pillars

The year of your birth (with its corresponding animal sign) represents only the most general of characteristics - i.e., those which may be shared with everyone who happens to be born in that year.

A much more detailed personal analysis is provided by exploring the Four Pillars of Destiny (八字, Ba Zi) which take into account not only the year, but also the month, day, and hour of birth.

Each of the pillars is made up of two characters: (1) a Heavenly Stem, representing the quality of elemental force, and (2) an Earthly Branch, representing the way this becomes manifested.

There are ten Heavenly Stems, each combining one of the five classical Chinese elements with either positive (Yang) or negative (Yin) energy.

There are twelve Earthly Branches. These correspond to the twelve signs in the Chinese Zodiac.

The Year Pillar

The Year Pillar represents the characteristics that you may expect to share with the cohort of people who are born in the same year. This pillar comprises the elemental energy of the year's Heavenly Stem and the typical manifestation of its Earthly Branch (the year's Zodiac Sign).

The Month Pillar

The month pillar represents your archetypal inner qualities, especially as these express a deeper, wiser or older self. It may also indicate characteristics that become more apparent in your later years.

The Day Pillar

The Day Pillar is generally the most significant. It indicates your everyday personality - the socialized version of yourself that you normally express and that other people experience and respond to. It may also suggest characteristics that become clearer in your adult years, or when you are at your prime.

The Hour Pillar

The Hour Pillar represents your natural, spontaneous, untutored self. Perhaps you usually keep this self private, holding back from expressing its qualities because they might appear childish or otherwise unacceptable. When under stress, or at times of crisis, you may find that your natural self tends to burst out uncomfortably. Alternatively, when you are fully relaxed, or in the company of children, it may express itself through play or creative activity.

Analysing your Four Pillars

Usually you will find interesting similarities and differences between the qualities expressed in your four pillars. Differences, in particular, should be considered carefully because these may indicate important conflicts and personal difficulties. Have fun exploring the various aspects of your personality and experience!
