Question: can rahu and ketu be atmakaraka?
Answer: (However other retrograde planets are calculated in the usual way) For e.g. if Rahu Ketu are 15º 24' in a chart, you minus this from 30º and the remaining degrees will be 14º36'. If this degree is greater than of any other planet, then Rahu Ketu will be considered the Atmakaraka.
