Dig Bala is the strength of planetary directions, i.e. their position relative to the angles of the chart.
Digbala has high influence on the effects of the planets.
Remark: It is difficult to determine the correct direction in which events will take place because there are different views of planetary directions. Digbala is the source of strength but events may take place in the directions attributed to the planets, i.e.
Each planet has directional strength in an angle of the chart. These points of strength are: the cusp of 1st house (Ascandant), 7th house (Descendant), 4th house (Nadir, Imum Coeli) or 10th house (Meridian, Medium Coeli).
Sun and Mars are strong in the 10th, Jupiter and Mercury in the Ascendant, Moon and Venus in the 4th and Saturn in the 7th.
Dig Bala of a planet is the distance between his position and the corresponding point of mimimum strength (in Virupas). Values greater than 180° or 60 Virupas must be deducted from 360° resp. 120 Virupas, so the Dig Bala of a planet must be between zero and 60 Virupas.
The table below shows the strongest and weakest points of Dig Bala for the planets.
digbala = ( 97° - 33° ) / 3 = 64/3 = 21 Virupas
digbala = ( 293° - 272° ) / 3 = 21/3 = 7 Virupas
