Is Ashtakavarga course available to listen to?
yes, its available on both sites.
I am looking at a Venus Ashtakavartga chart and Venus has 3 points so mediocre. But the 10th from Venus has 8 points (perfect score), and 11 from Venus has 6 points as well as 8th from Venus also has 6 points. What can i interpret from these points?
High point signs are more auspicious, so meeting a girl from the direction of a high point sign will indicate greater compatibility. Then when venus transits these signs, venus things will do better.
If the 10th house from Venus has the highest point then per what you said above when Venus transits the 10th house Venus will do great. For transit, do you look at the transit chart to see when Venus is in the 10th house of the transit chart? Or do you look for when Venus is in the 10th house of the Rasi Birth chart to make this prediction?
