Zodiac can be defined as a circle of animals. It has 12 partitions or we can say “sun signs” in western astrology. The signs represent the symbols for an everlasting cycle of growth and transformation of life. The signs also define the polarity in the zodiac. Polarity means positive or negative. Some signs behave as a positive sign and these people are outspoken or outgoing and some behave as a negative sign and these people are soft spoken or quiet.
