Six upagrahas called Kaala, Mrityu, Arthaprahaara, Yamaghantaka, Gulika and Maandi are more difficult to compute. Kaala is a malefic upagraha similar to Sun. Mrityu is a malefic upagraha similar to Mars. Arthaprahaara is similar to Mercury. Yamaghantaka is similar to Jupiter. Gulika and Maandi are similar to Saturn. A day starts at the time of sunrise and ends at the time of sunset. A night starts at the time of sunset and ends at the time of next day’s sunrise. Depending on whether one
is born during the day or the night, we divide the length of the day/night into 8 equal parts.
8 When adding or subtracting longitudes, we should subtract 360° if we get more than 360° and we
should add 360° if we get less than 0°. Adding or subtracting 360° means going around the zodiac
once and coming to the same position. We should finally reduce all longitudes to a value between 0°
and 360°, by adding or subtracting 360° as many times as needed.
Daytime births: The first part is ruled by the lord of weekday and then we cover planets in the order of weekdays. The part after the one ruled by Saturn is lord-less. After that, Sun’s part comes. For example, the first 1/8th of the daytime on a Thursday is ruled by Jupiter. Next part is ruled by Venus. The 3rd part is ruled bySaturn. The 4th part is lord-less. The 5th part is ruled by Sun. The 6th part is ruled by Moon. The 7th planet is ruled by Mars. The 8th part is ruled by Mercury.
Night time births: The first part is ruled by the 5th planet from the lord of weekday and then we cover planets in the order of weekdays. For example, the first 1/8th of a Thursday night is ruled by the 5th planet from Jupiter, i.e. Moon (Jupiter, Venus, Saturn, Sun, Moon – that’s the 5th one). Next part is ruled by Mars. The 3rd part is ruled by Mercury. The 4th part is ruled by Jupiter. The 5th part is ruled by Venus. The 6th part is ruled by Saturn. The 7th planet is lord-less. The 8th part is ruled by Sun.
Table 10 gives the list of the ruling planets of all the eight parts of the daytime and night time on all weekdays.
Once we divide the day/night of birth into 8 equal parts and identify the ruling
planets of the 8 parts, we can find the longitudes of Kaala etc upagrahas using the
following procedure:
(1) Kaala rises at the middle of Sun’s part9. In other words, we find the time at the middle of Sun’s part and find lagna rising then. That gives Kaala’s longitude.
(2) Mrityu rises at the middle of Mars’s part.
(3) Artha Praharaka rises at the middle of Mercury’s part.
(4) Yama Ghantaka rises at the middle of Jupiter’s part.
(5) Gulika rises at the middle of Saturn’s part.
(6) Maandi rises at the beginning of Saturn’s part.
Suppose one is born on Thursday night and we want Yamaghantaka’s longitude in his chart. Suppose night starts at 6 pm and ends at 6 am on the next day. We see from the table that Jupiter rules the 4th part of a Thursday night. Each part is 12/8 = 1.5 hours. The 4th part starts 4.5 hours after sunset, i.e. at 10:30 pm, and ends 1.5 hours later. So Jupiter’s part extends from 10:30 pm to midnight. The middle point of this part is at 11:15 pm. We find lagna rising at 11:15 pm and that will be Yama
Ghantaka’s longitude.
