Hindu astrology is not very different as our in Occidental countries. The only difference is that precessional distance is taken into account. Hindus draw a horoscope in a square fashion, and don't take into consideration the new planets, Uranus, Neptune, Pluto. On the other hand, Moon node (Rahu and Ketu) are of high importance. Aspects are by sign. For example, in the horoscope below all planets in Leo are aspected by Saturn. Hindu approach is fairly rational and they try to measure the strength and quality of planets in the studied horoscope. Calculations are difficult and tedious. That is why a computer can be useful. You can then try their method and decide if they are right for you.
