Leo Lagna (Simha) is the fifth ascendant template, ruled by Surya (the Sun). As a fixed fire sign, Simha represents sovereign authority, creative self-expression, loyalty, and a natural instinct to lead and protect.
The Sun as Lagna Lord grants these natives a radiant Pitta constitution, a strong skeletal system, warm metabolic heat, and a commanding posture. They possess strong digestion and high innate immunity.
Mars rules the 4th and 9th houses, acting as the Yogakaraka for Leo rising. This links their domestic happiness and spiritual dharma directly to courage, land development, and administrative duty.
