Drekkana (D3 chart)
The Drekkana (D3) divides each sign into three parts of 10°. It is the divisional chart for siblings, courage, initiative and the results of your own efforts.
Also known as: drekkana chart, drekkan, dreshkana, decanate, d3 kundli
In Parashara’s method the first 10° of a sign stay in that sign, the second 10° go to the 5th sign from it and the last 10° to the 9th, so each drekkana keeps the element of its sign. Western astrology’s decans rest on a similar idea.
Parashara reads “happiness through co-born” from the D3: brothers and sisters, the help they give and the bond you share. Astrologers also use it for courage, energy and enterprise, and each of the 36 drekkanas has a classical image used in detailed work.
Its ascendant changes about every 30–45 minutes, so it is more forgiving of small birth-time errors than the higher divisions. Read it with the 3rd and 11th houses of the Rashi chart and with Mars, the karaka of siblings.
