What is Kendradhipati Dosha?
Kendradhipati Dosha is a subtle rule from classical texts: a natural benefic that owns a Kendra (the 1st, 4th, 7th or 10th house) loses some of its benefic power, while a natural malefic owning a Kendra gains. It is strongest for Jupiter and Venus and is one reason a "good" planet may underperform.
