Dear WebYogi,
Thank you for your kind response, but according to the rules of manglik cancellation,
When Mars is in its own sign (Aries, Scorpio), exalted
> (Capricorn) or in the houses owned by PLANETS SUPPOSED to be his
> friends (Sun, Jupiter, Moon) manglik dosha gets cancelled.
In this case it is vrishchik lagna, and mars is in the second house - dhanu - whose lord is jupiter.
So mars being in the house of his friend Jupiter as specified above should surely lead to a cancellation of the debilitation? If you do not agree, may I please request why this is so?
