The Lower Lines

May there be prosperity! This describes the method for the Trine Reduction Sanskrit: Trikona Shodhana; a process of simplifying astrological points based on the three signs belonging to the same element for each of the eight charts mentioned in the Ashtakavarga Jataka. The first, fifth, and ninth houses are mutually trine houses. Among these trines, whatever value is the lowest should be subtracted from all three. If one house contains a zero, no reduction is performed in that trine. ||1|| If the values are equal in all houses, the wise practitioner should reduce them all to zero.

Now, the method for the Reduction of Dual Lordship Sanskrit: Ekadhipatya Shodhana; a second reduction based on planets that rule two different zodiac signs applied to the lines already purified by the trine reduction.

The wise should reduce them when there are results in both fields.

If one sign is occupied by a planet and the other is empty, the reduction is performed alongside the diminished one. This is one variation. ||1|| Among the planets...
