Moon is considered as mind in Vedic astrology. Normally mind is very volatile in nature. As we know Moon expands and contracts in space as perceived from Earth. True to its nature, the mind also changes its nature. In astrology also, the Moon needs some support from other planets for stable mind. It is preferable to have planets near Moon in the chart for better results. If it is sitting alone in a horoscope without any planets in either side of the Moon, then the mind will be fluctuating and it leads to Kemadruma yoga.
When a planet other than the Sun occupies the second house from the Moon, it results into the Sunapha Yoga. There can be some 31 different permutations of Sunapha Yoga possible.
According to Parashara Hora and Phaladeepika, the native with Sunapha yoga will be a king/equal to a king, will have acquired property, will be respected and famous for his intellectual abilities, will be rich and well reputed.
According to Varahamihira, the native will be rich because of his self earned wealth, will be a king, famous and wealthy.
Sunapha yoga can be formed by one or more of Mars, Mercury, Jupiter, Venus and Saturn are placed in 2nd house from Moon. So the result will depend on the planet associated.
If Sunapha yoga is formed when Mars is sitting in 2nd house from Moon, the native will be courageous, hard working, valorous, wealthy, powerful, rude, cruel in speech, can be army chief, will always oppose others.
If the yoga is formed with Mercury, the native will be intelligent, skilful, expert in Vedas, shastras, a poet, will be handsome, beautiful, always does good to others, will have religious inclination.
If Jupiter causes the Sunapha yoga, the native will be a teacher, will excel in learning, a king or be favoured by the ruler, wealthy, blessed with a good family.
If Venus causes this yoga, the native will have material comforts, good in looks, blessed with wife, land, vehicles, likes to wear beautiful clothes.
If the yoga is formed by Saturn, the native will be wise, respected by the people, he will be skilful and devoted to his work, but the combination is not favourable for mother of the native.
The result of the yoga is modified due to the aspect and association from other planets. Also the lordship of the houses and strength of the planets alter the results. We have to take considerations of all these factors while analysing.
There can be 31 different combinations of Sunapha yoga possible by five planets.
Five combinations are possible in which only one planet occupying second house from Moon. Ten combinations are possible when two planets occupy. Again ten combinations are possible with three planets. Five combinations are possible with four planets and one combination is possible from one planet.
