The sarvāṣṭakavarga, each graha’s bhinnāṣṭakavarga and the full prastāra, house by house, for your rāśi chart or any divisional chart, calculated the way Jagannātha Horā does it.
How it works
Each of the seven grahas and the lagna gives a bindu, a benefic point, to certain houses counted from where it stands. A graha’s own aṣṭakavarga, the bhinnāṣṭakavarga, collects the bindus the eight givers put in each sign, and the prastāra shows which giver put each one there. The sarvāṣṭakavarga adds up the seven grahas’ tables, 337 bindus in all.
The bindu tables are the ones Jagannātha Horā uses; they reproduce the worked examples in its author’s textbook. Sārāvalī gives the Moon’s table differently in three places, for the 9th from the Moon, the 9th from Mars and the 2nd or 12th from Jupiter, so software that follows it can show a different Moon column. The lagna’s own table is shown too but, as in Jagannātha Horā, it is not added to the sarvāṣṭakavarga.
For a divisional chart the same tables are applied to the signs the grahas and lagna occupy in that chart. The vargas follow Jagannātha Horā’s default rules, which are Parāśara’s for the sixteen vargas he gives. Positions use the True Citrapakṣa ayanāṁśa. Nothing you enter here leaves your browser.
