Лунные стоянки (накшатры)

Откуда это берётся

Брихат Парашара Хора Шастра — глава 3, стих 4-6

Дословно, в английском переводе с санскрита

Those are called ‘Grahas’, that move through the Nakshatras (or stellar mansions) in the zodiac. The said zodiac comprises of 27 Nakshatras commencing from Ashvini. The same area is divided in 12 parts equal to 12 ‘Rāśis’ commencing from Mesh. The names of the Grahas commence from Sūrya. The Rāśi rising is known, as ‘Lagn’. Based on Lagn and the Grahas, joining and departing from each other, the native’s good and bad effects are deducted. Addition from Santhanam till Sloka 7. The names of the 27 Nakshatras are Ashvini, Bharani, Krittika, Rohini, Mrigasira, Ardra, Punarvasu, Pushya, Aslesha, Magha, Purvaphalguni, Uttaraphalguni, Hasta, Chitra, Swati, Vishaka, Anuradha, Jyeshtha, Mula, Purvashadh, Uttarashadh, Shravana, Dhanishtha, Satabhisha, Purvabhadra, Uttarabhadra, Revati. Lagn is a very important point in the horoscope. It is the Rāśi, that rises in the East, on the latitude of birth. The apparent rising of a Rāśi is due to the rotation of the earth on its own axis at a rate of motion, causing every degree of the zodiac seemingly ascend on the eastern horizon. Approximately, two hours are required for a Rāśi to pass via the horizon, thereby every degree taking four minutes to ascend. This duration, however, is actually dependent on the concerned latitude. Actually Sūrya has no motion. His motion is an apparent one, as viewed from the rotating earth. Other Grahas, including the nodes, have varied rates of motion. The average daily motions of the Grahas, which are not, however standard, are, as follows: Sūrya 1, Candr 13- 15, Mangal 30-45’, Budh 65-100’, Śukr 62-82’, Guru 5-15’, Śani 2’, Rahu/Ketu 3’. With such different motions, a Grah forms various Drishtis with others. These Drishtis through longitudinal distances have a great deal of utility in Jyotish. This is what Maharishi Parashar suggests to be considered.

Отсюда берутся сами накшатры: зодиак разделён на 27 участков, счёт идёт от Ашвини, и планеты идут по ним одна за другой. Всё, что говорится о накшатре, стоит на этом делении — и наши границы посчитаны по нему же.
