One important use of naxatras in jyotish is one simple tool for finding out auspicious and inauspicious year for a native. This tool goes by the name of Tripapa Chakra and the objective is to find years lorded by three malefics, hence the name Tri-Papa which means three malefics. The year so lorded by three malefics are inauspicious and troublesome.
This tool even though is not given in a any known classics, have been in use in certain parts of India such as West Bengal for time immemorial. This too is used for finding out the auspicious and inauspicious years in conjunction with the dasas such as the Vimshottari dasa. During an unfavourable dasa, if the year lords happen to be malefics according to this chakra, then the native suffers untold suffering.
The basis of this tool is three chakras namely, the Ketu Pataki Chakra, the Ketu Kundali Chakra and the Guru Kundali Chakra. As per these three chakras, different planets are assigned to each naxatra (based on 27 naxatra scheme). Based on the birth naxatra of the native different planets become the year lords as per the sequence of planets given onthe chakra. For example the sequence of year lords as per the Ketu Pataki Chakra is Sun, Moon, Mars, Mercury, Saturn, Jupiter, Rahu, Ketu and Venus.
If the year lords as per the three chakras are predominantly benefic, the year will be auspicious while predominance of malefics shall make the year in-auspicious and troubles ridden.
Work in progress.
