Guest guest Posted November 7, 2001 Report Share Posted November 7, 2001 Hi, I am trying to compute these special lagnas and I have one question reg= arding bhaava lagna, I'm wondering if a step was left out in the instruction= s. After finding the minutes from sunrise to birth, should I divide by 4 fi= rst and then add the sun's longitude at sunrise?

Thanks, Angie You are absolutely right, as bhava lagna moves with half the speed of hora lagna. It's a shame that the same error has gone into my book unchecked. :-( The procedure for hora lagna and ghati lagna is correct. But bhava lagna is wrong. Divide the minutes since sunrise with 4 and add those many degrees to Sun's position at sunrise. Thanks for correcting. May Jupiter's light shine on us, Narasimha Quote Link to comment Share on other sites More sharing options...
