Vedic Astrology has a unique system of determining the compatibility
between two charts. Chart compatibility is determined by precise
analysis of how the planetary positions in the charts compare and
interact. Traditionally, the position of the Moon is considered the
most important factor, and a scoring system based on the Moon has become
very popular in India. Since the Moon is so significant for how our feelings
operate, and relationships are predominantly based on feelings, there is no
doubt that the Moon plays a major role. A good Moon compatibility will
generally indicate a good emotional/mental fit.
There are several aspects behind a compatibility calculation like
work, dominance, destiny, mental harmony, health and mutual love,
but together they form an optimal situation.
