In Anfa Yog if there is one or more than one planet present in 12th house from the house of Moon in a horoscope. This Yog can bless the native with good health, fame and spiritual progress. Some astrologers believe that the presence of Sun in 12th house from Moon is an exception to the formation of Anfa Yog which means that if Sun alone is present in 12th house from Moon in a horoscope, Anfa yog is not formed in such a horoscope and Sun must be present along with one or more than one planets in a horoscope in order to form Anfa yog in the horoscope. For good results of Anfa yog, Moon should work as benefic planet in the horoscope and a malefic Moon is not likely to make an Anfa yog in the horoscope.
The presence of malefic planets in 12th house from Moon in a horoscope can also dilute to good results related with Anfa yog and for Anfa yog to produce best results in a horoscope, Moon as well as the planets present in 12th house from Moon should be benefic planets for that horoscope. The placement of Moon with one or more than one malefic planets in a horoscope or the aspect of one or more than one malefic planets on Moon in a horoscope can also reduce the benefic results of Anfa yog and best results of Anfa yog are experienced when Moon is placed alone or it is placed with benefic planets in a horoscope and the planets placed in 12th house from Moon are also benefic. It should also be noted that the strength and placement of Moon in a horoscope is also an important factor while predicting the benefic results of Anfa yog in a horoscope as the presence of a benefic Moon in Taurus sign makes a much stronger Anfa yog than the one formed due to presence of Moon in the sign of Scorpio which is the sign of debilitation for Moon and as Moon becomes weak in the horoscope, Anfa yog also becomes weak in the horoscope.
