| Diurnal & Nocturnal Strength ( Divaratri Bala ) | | | | Paksha Bala of Benefics = LongMoon - LongSun /3 |
| This is the strengths of planets due to diurnal or | | | | Paksha Bala of Malefics = 60 - Paksha Bala of |
| nocturnal influences. Known as Divaratri Bala, it consist | | | | Benefics ( in Shastiamsas ) |
| of Diurnal Strength ( Diva Bala ) & Nocturnal | | | | The Paksha Bala of the Moon is always to be doubled. |
| Strength ( Ratri Bala ). | | | | Equations for 60 Degrees Strength ( Thribhaga Bala ) |
| The nocturnal planets - Moon, Saturn & Mars are | | | | Divide Day ( Ahas ) & Ratri by 3 ( 180/3 = 60 |
| powerful during midnight and powerless during midday. | | | | degrees ). 60 degrees is a Thribhaga. |
| ( Nishi Sasi Kuja Saura Sarva nJne ) and 60 | | | | Mercury, Sun and Saturn rule the Thribhagas of the |
| Shastiamsas are assigned to them at midnight as their | | | | Day |
| Divaratri strength . On the contrary, the diurnal planets - | | | | Moon, Venus & Mars rule the Thribhagas of the |
| Sun, Jupiter & Venus - are powerful during midday | | | | Night |
| & powerless at night and 60 Shashtiamsas are | | | | Find out the Thribhaga when birth has occurred. Assign |
| assigned to them at midday as their D R strength. | | | | 60 Shastiamsas to the ruling planet of that Thribhaga. |
| Powerful always is Mercury, be it day or night & | | | | Assign 60 Shastiamsas to Jupiter, who always gets |
| he always gets 60 Shastiamsas. | | | | 60 Shastiamsas ! |
| Midday & Midnight | | | | So only 2 planets gets Thribhaga Bala of 60 |
| While Midday is defined as the LMN ( Local Mean | | | | Shastiamsas ! |
| Noon ), the Seers have recommended that if the birth | | | | So you will find that Mathematical Astrology is not |
