Ashwini

Ashwini opens the zodiac, and everything about it carries the quality of a beginning: quick, unweathered, moving before it has finished thinking. The Ashwini Kumaras of the tradition are physicians who arrive at speed, and the pairing of healing with haste is the whole character of the division. It starts things well and finishes them less often.

Ketu rules it, which sharpens rather than softens that. Ketu has no interest in accumulation, so an Ashwini moon tends to move on from what it has built without much regret. Read practically, the useful question for someone with weight here is never how to become faster. It is what they abandon at the point where the first excitement runs out, and whether they can build one habit of returning to it.
