The Drekkana (D3) divides each 30° sign into three 10° parts, with each part mapping to a sign of the same element. The first decanate maps to itself, the second to the next sign of the same element, the third to the third sign of the element. Aries, for instance, splits into Aries-Leo-Sagittarius across its three decanates.
Classical sources read the Drekkana as the chart of the 3rd house — siblings, courage, short journeys, hands-on effort, and the kinds of efforts the person makes through their own initiative. Strong benefics in the Drekkana indicate good relationships with siblings and reliable courage; afflicted planets there indicate sibling rivalries or difficulty with self-effort.
The Drekkana is one of the more frequently consulted specialised vargas because the 3rd-house domain is broad — it includes communication, neighbours, short trips, and the day-to-day muscle of getting things done. Practitioners read it whenever those domains are in question in a chart.
How to read it
Look at the Lagna of the Drekkana, then planets in the 3rd house of the Drekkana, then the 3rd-house lord of the Rasi as placed in the Drekkana. Together they describe the person's sibling relationships and capacity for self-driven effort.
Pitfalls
Don't confuse the Drekkana with the Western decan system — the rulership rules are different even though both subdivide signs into three.

The free Vedic birth chart computes D1 + D9 by default; the paid chambers expand to the full Shodashavarga when the reading calls for it. Pull up your chart and see how the Drekkana maps your siblings, courage, short journeys, self-effort domain.

Each sign split in three — the chart of siblings, courage, short journeys, and self-effort. The Drekkana divides each 30° sign into 3 parts and re-maps the planets accordingly to zoom in on the domain of siblings, courage, short journeys, self-effort.
Each 30° sign splits into three 10° parts. The three parts map to the three signs of the same element (e.g. Aries → Aries / Leo / Sagittarius).
