This is the discussion summary, I send to people.. on Punarphoo Dosa. (Punarphoo in Tamil means, conjugal)
Malefic effects (marraige and Health only) Sat-Ven-Moon.
For Punarphoo we have to look at 4, 8, 10, 12 and with strong Saturn (RP), with Venus affliction, and under the Moon period, delays happen (note 2, 7, 11 not in picture). Few add more house too. In fact, all the 12 houses, with have these 3 planet combinatons some point of time. I have seen on that with Mars too! But not all in Sat DBA. There are verious combinations to look at.
When someone hears, that he has dosa, he puts blame on destiny and moves on. This is traditonal astrology. Nice placebo effect.
