Libra rules the kidneys in the physical body. Libra is ruled by Venus, and its symbol is the Scale. Libra is an Air sign, charming and balanced. This is the ' union' or marriage sign of the zodiac, and the soul can no longer function in the 'me' consciousness. It has to become the 'we' consciousness.
Relationships are seen as the purifiers of the consciousness, for no man can be an island.
Venus rules this sign. Only through love and cohesiveness can true union be attained. The development of relationships is the most important attainment for the Libran. The Libran finds it difficult to be generous, for he is tenacious and Saturn is exalted in this sign. Librans are secretive about finances and personal matters and will resent any attempt to pry into their affairs.
