It is a fiery sign ruled by the Sun, the significator of vitality, intelligence, male progeny, social status and magnificence. These factors render the Leos noble hearts, with character and will power. If Leo rises as the ascendant, the Ishta Devata (form of god for worshipping and meditation) would be mother divine, Goddess Durga. This sign rules upper belly, stomach, spine, spinal cord, back, liver, gall bladder, spleen and pancreas. If the Sun is strong, the Leos enjoy good health. Otherwise, they are vulnerable to the diseases of heart, spine, back, bones, spleen, pancreas, liver, stomach, weak digestion, fevers, etc., and lack stamina and will power. This is the mooltrikona sign of the Sun.
