Rashi chart (D1, Lagna chart)
The Rashi chart (D1), or Lagna chart, is the main birth chart: the twelve signs arranged from your ascendant, with each planet in the sign it occupied at birth. Every other chart refines it.
Also known as: rasi chart, d1 chart, lagna kundli, janma kundli
In the Rashi chart each house holds one whole sign, beginning with the ascendant’s sign as the 1st house. It shows the planets’ signs, houses, aspects, conjunctions and dignities, and from it come the house lords and most yogas. Parashara reads the physical self from it, and astrologers treat it as the foundation of every judgement.
Divisional charts, above all the Navamsa (D9), are read alongside it to confirm and fine-tune its promises. The Chandra Kundli is the same chart redrawn from the Moon, and the Bhava Chalit adjusts its houses to the exact degree of the ascendant.
Because its ascendant changes only every couple of hours, the Rashi chart is fairly robust to small errors in birth time. Even so, an ascendant or planet in the first or last degrees of a sign needs care.
