Ketu in the 12th is a classical placement for moksha: spirituality, meditation and liberation, with expenses on spiritual pursuits.
What the 12th house governs
The 12th house, Vyaya bhava, covers expenses, losses, foreign lands, sleep, isolation, charity and liberation. It is a dusthana (difficult) house, linked with obstacles that build resilience.
What Ketu brings
Ketu is the south lunar node. It represents detachment, past-life skills, spirituality and liberation (moksha).
What changes the result
- Sign and dignity: Ketu exalted or in its own sign gives the best version of this placement; debilitated or in an enemy sign, the weaker version.
- House lordship: which houses Ketu rules for your Lagna decides whose matters it carries into the 12th house.
- Aspects and conjunctions: Jupiter's aspect protects; Saturn, Mars or Rahu add pressure.
- Dasha: the placement shows most strongly during Ketu's own Mahadasha or Antardasha (7-year Mahadasha).
