Planetary combinations  or Yoga :

Mostly Western astrologer  used to different aspects and directions for their forecasts . mostly they are used  the Tajika shastra and most developed and advanced scientifically method. But The Hindu system or Indian system of prognostication depends mostly on Planetary combinations. The Planets when posited in a particular fashion or house in a birth chart, produce  particular results. The number of such planetary combinations is very large, as there is no limit to their permutations and combinations but mostly about 1001 combinations or Yoga are used in astrology in india.                                                            Indian astrologers have classified that different planets as benefic and malefic and some different  signs are cruel  and benevolent. They have divided different houses also as  favourable and unfavourable.

1.  Trines, houses like  1,5,9                  –    best.
2.  Quadrants, houses like , 1,4,7,10, —   good.
3.  Houses   2,3,11                                       –   Not so good.
4.  Houses , 6,8,12 or the Tricks ,       —  Bad.

So there is interaction between best good and even not good gouses and their lords, favourable results may be expected. Where Trick houses and their lords intervene, they not only nullify good results, but sometimes produce adverse results as well. The nature and the subject of the result depend on the significatorships of the houses and the planets. Their extent depends on the strength of the planets.

As  for the special combinations, they may be classified as under :

1. Combinations  based on Ascendant.
2. Combinations based on Moon.
