Generally in janamkundli combination of Sun with Rahu-Ketu is known as Pitra Dosh but in palmistry if lifeline is straight and island on bracelet then this indicates Pitra Dosh.
Also there is a Matra Dosh similar to Pitra Dosh, if your headline goes downward parallel to lifeline and ends on Mount of Ketu or Mount of Moon and there is a island on bracelet then this indicates Matra Dosh.
If you are suffering from Matra Dosh (Matra Dosh in your janamkundli or on your hand) then you need to stick or hang Maruti Yantra on south wall of your bedroom or house. Also you need feed jaggery to cow on daily basis.
