Yogas in vedic astrology

In Hindu astrology, yoga is the relationship between one planet, sign, or house to another by placement, aspect, or conjunction. It is the consideration of the planetary dasha's directional effects, the most important factor which distinguishes Hindu astrology from Western astrology.

Mahapurusha Yogas:

Mahapurusha Yoga is a planetary combination, which indicates great people. It occurs when planets are located in their own signs or exalted and at the same time in angle from Ascendant or Moon. Only 5 major planets are considered, not the Sun or Moon. Such positions serve to magnify the quality of the planet.

Lunar Yogas:

An unassociated Moon is generally inauspicious, often if she is otherwise well placed. Moon does well I conjunction with benefic planets or with benefics in adjacent signs. It does better if Jupiter is located in angle from her (Gaja Kesari Yoga). When Moon aspected or hemmed in by malefics, particularly Saturn and Rahu, then emotional mind (manas) may suffer.
