Ṣoḍaśavarga · the sixteen divisions

षोडशवर्ग

The divisional charts — subdividing the sign to see what the sign conceals

A varga takes each 30° rāśi, cuts it into equal parts, and maps every part onto a sign of the zodiac by a fixed rule. The result is a second chart, read for one department of life. The sixteen nest rather than merely accumulate: the ṣaḍvarga of six sits inside the saptavarga of seven, inside the daśavarga of ten, inside the ṣoḍaśavarga of sixteen — and each grouping carries its own Viṃśopaka weighting out of twenty, so the same varga counts differently depending on which set you are working in.

Viṃśopaka weights

Each column totals twenty. A varga's importance is not fixed — the navāṃśa is worth 5 of 20 in the ṣaḍvarga scheme and only 3 in the ṣoḍaśavarga, where the ṣaṣṭyāṃśa takes the largest share after the rāśi chart itself.

Varga dignity names

When a graha falls in a favourable sign across several vargas at once, the classics give the resulting condition a name. The count runs from two upward, and the naming set differs by which grouping you are using.

Reading the division bar. Each bar is one 30° rāśi — whichever you have selected above — cut into that varga's parts, with every part labelled by the sign it maps to and tinted by that sign's tattva. Parts that map back to the sign you started from are outlined in white: a graha there is vargottama in that varga. Change the selected sign and every bar on the page redraws.

On the computation rules. These follow Bṛhat Parāśara Horā Śāstra chapters 6 and 7. Several vargas have variant rules in circulation — the daśāṃśa starting point for even signs, the horā scheme (Parāśara's differs from the Jaimini form), and the ṣaṣṭyāṃśa name-set all vary between lineages and between software packages. Where your software disagrees with a bar here, check which convention it is using before assuming either is wrong.

The precision problem is real. A D-60 division is 30′ of arc, which the Moon crosses in about an hour and the ascendant in roughly two minutes. Without a rectified birth time the higher vargas — D-40, D-45, D-60 especially — are arithmetic rather than astrology. Parāśara nonetheless assigns the ṣaṣṭyāṃśa the heaviest weight of any varga but the rāśi chart, which is a tension the tradition has never fully resolved.

The governing principle. A varga refines what the rāśi chart offers; it does not create what the rāśi chart withholds. A brilliant navāṃśa over a broken 7th house describes the quality of what little there is, not an abundance hiding behind the surface.
