Gulika A mathematical point in a horoscope considered the "son of Saturn," used in Vedic astrology to identify specific karmic influences., Mandi Another sensitive point related to Saturn, often used interchangeably with Gulika but treated distinctly here., Sage Mandavya A legendary ascetic mentioned in the Mahabharata, credited here with specific astrological doctrines., Ishtakala The elapsed time from sunrise to the moment of birth., Ascendant Calculation The process of determining the zodiac sign rising on the eastern horizon., Zodiac Sign, Degrees, Minutes, Seconds, Day-duration, Night-duration, Lord, Lord of the Day
The eighth portion is without a lord. During the day, the portion belonging to Saturn is called Gulika. If the birth occurs at night, the lords of the seven portions of the night follow the aforementioned sequence; however, the lord of the first portion will begin from the lord of the fifth day counted from the day of birth. Here too, Saturn's portion is understood as Gulika, but Gulika represents the very end of Saturn's portion. These two sons of Saturn—namely 'Gulika' and 'Mandi'—are of an extremely wicked nature according to the opinion of Sage Mandavya. Wherever they are situated, they cause harm to that house. In ancient texts, Mandi and Gulika are sometimes considered to be the same. The majority opinion favors this view. However, the author here, basing his work on the opinion of Sage Mandavya and indicating through the use of the dual noun form, has treated them as two distinct entities. Therefore, for Mandi, one should multiply the Ishtakala time of birth by the numbers specified according to the day of birth, divide the product by 30, and based on the resulting ghatis and palas traditional units of time where 1 ghati = 24 minutes, calculate the zodiac sign, degrees, minutes, and seconds of Mandi just as one calculates the Ascendant.
Regarding Gulika, keep in mind that the segment of Saturn on the day of birth is called Gulika. For this, the day-duration should be divided into eight equal parts. The lord of each part is identified by counting from the day of birth. Whichever part belongs to Saturn is Gulika. At night, divide the night-duration into eight parts and count from the fifth day from the day of birth to find Saturn's segment; that Saturn-segment will be Gulika. A simple method is this: divide the day-duration or night-duration of the day of birth by eight. That eighth part is called one "segment." During the day, the lord of the first segment is the Lord of the Day, and at night, the lord of the first segment is the fifth planet from the Lord of the Day. Now, write down the value of this one segment in one place. Then, counting from the day of birth, see at what number Saturn falls. For example, on Sunday it is at the seventh position, on Tuesday at the fifth, on Wednesday at the fourth, and so on. For a night birth, count from the fifth planet from the day of birth. Whatever number Saturn falls on, multiply the aforementioned segment-value by that number. The resulting product will be the "Ishta" calculation point for Gulika. If you calculate the Ascendant using this Ishta time, the precise longitude of Gulika will be known. For example, if one wishes to find Gulika on a Tuesday for a day birth, and the day-duration is 28 ghatis—
