Few years back, an astrologer saw my jaataka and said to me that I have randhreswari yoga. I did not ask him what it is at that time, as i was thinking about other details he said. But now when I remember it, i want to know more about it. I understand that it is something good, but dont know exactly what it is. Do I need to do any japa or puja to enhance its power? Any one knows about it?
