Niṣeka and Ādhāna are separate events in the creation of a baby. Niṣeka (निषेक) literally means sprinkling, infusion, dripping and refers to the seminal infusion which leads to impregnation and the vedic ceremony connected with it. Ādhāna (आधान) is better understood from the word garbhādhāna where garbha means womb. It means depositing, placing or impregnating and refers to the place in which anything is deposited or rests, which in the context of birth is the womb. Impregnation or fertilization of the ovum happens after coitus (niṣeka) and can be as far apart as seven days. Many astrologers have come up with various innovative schemes and calculations for knowing this. Yet the method of the great master Parāśara remains the best and most accurate. If you ponder at the philosophy behind those calculations, there would be a lot to learn.

  • Lesson-01: Māndi - Māndi Determination Divide the day duration [sunrise to sunset] into 8 parts [8 petal lotus]. Each part is called velā.

  • Lesson-03: Niṣeka Lagna - From the previous lesson, please note that by now we have two niṣeka dates/times and we can draw charts for these dates. Pregnancy Period Test Both the niṣeka periods are (a) 298 days 8h01m46s and (b) 278 days 1h02m35s. The full term of the niṣeka period is 273 days and all the niṣeka times obtained […]

  • Lesson-07: Ādhāna Lagna - {tab=Exact Ādhana} Exact Ādhana Lagna We are now in a position to calculate the exact time of the Ādhāna and should forsake the approximate methods obtained previously. While those methods based on niṣeka period in days and solar motion help us to arrive at the date, it is necessary for the sake of studying the […]
