Signification of Signs
Briefly, the significations of the various signs are discussed here:
ARIES : It is a fiery sign ruled by Mars, the significator of energy. The Sun, the significator of vitality, is exalted in this sign. Saturn, the planet of lethargy, becomes debilitated in this sign. These factors render the Arians most active, strong, aggressive and healthy in case Mars is strong. If Aries rises as the ascendant, the Ishta Devata (form of god for worshipping and meditation) would be mother divine, Goddess Durga. Worshipping the Ishta Devata would help in spiritual evolution and in maintaining mental peace. This sign rules head (cranium and forehead) and brain. If Mars and Mercury are strong, the Arians enjoy good health. Otherwise, they have a sickly constitution, suffer from wounds, headache, mental tension, fevers, short-temperedness, insomnia, diseases of impure blood, bilious diseases, inflammatory disorders, constipation, stammering, etc. Aries is the mooltrikona sign of Mars.
