The Ketu dasha
the seven year Ketu mahadasha in the Vimshottari sequence, the traditional starting period of the cycle
What the tradition reads
In the Vimshottari system, Ketu, the south lunar node, governs a period of seven years, tied with Mars as the second shortest of the nine, and is the period the traditional sequence is counted from first. Like Rahu, Ketu is not one of the seven classical planets and has no physical body, and Phaladeepika's reading of its dasha leans harsh: trouble from enemies, from thieves and from those in authority, wounds from weapons, disease brought on by excessive heat, disgrace within the family, danger from fire, and even exile from one's own place. The tradition treats Ketu as a shadow point associated with detachment, spiritual insight and the letting go of what a person has already built rather than the pursuit of anything new, so a Ketu dasha is read as a period that tends to strip away rather than add, whether that stripping is experienced as loss and disruption or, where the rest of the chart supports it, as a genuine release into renunciation, introspection and a narrower, more spiritual focus. Its brevity is itself read as fitting: a short, sharp period rather than a long, steady one, suited to a planet the tradition treats as having nothing solid left to build with in the first place.
The story
Ketu shares its origin with Rahu in the story of Svarbhanu, an asura who disguised himself among the gods during the churning of the ocean of milk to steal a share of the nectar of immortality. The Sun and Moon saw through the disguise, and Vishnu, in his female form Mohini, cut off the asura's head with the discus Sudarshana before the nectar could pass fully down his throat; the head lived on as Rahu, and the headless body as Ketu, neither able to die because the nectar had already been tasted. Where Rahu is pictured as a head or a dragon still hungry for what it cannot swallow, Ketu is pictured as a body without a head, often riding a vulture, an image the tradition reads as a personification of renunciation itself, a form that visibly needs nothing more because it no longer has the means to consume anything at all. A period ruled by a torso that survived its own beheading, in the tradition's reading, is a period about what remains when appetite itself has been cut away.
