Thanks for sharing an interesting post. Since, I don't know much about astrology/houses and all, so I will not comment on that aspect.
But, as I understand reading the blog, the gist of it says that, Yudhistir intentionally destroyed his poorva punya.Assuming Yudhistir had +100 in his Poorva Punya account and then he committed sins by staking his brothers/wife in dice game and thus accrued -100 in his current account, thereby cancelling out the plus/minus in his respective accounts to ensure he doesn't take any more births in future. Not sure, this aspect could be the reason for Yudhistir's decision. If that is so, then it could be termed as pretty selfish decision on Yudhistir's part, just to relieve himself of not taking any future births, he caused severe distress to his wife and brothers in the process.Actually, I feel your earlier post regarding karma and saguna brahmana and so on, makes more sense to me, than this poorva punya concept of reduction on will and thus foregoing future births.Thus reading earlier posts, the one which makes sense to me is, we will have births, till we have exhausted all our bad deeds/sins in all our previous births by cancelling out with good deeds. So, to me, at all times, in the account it will be -ve and only when the current total becomes 0/+ve, we will not have any more births and attain liberation.
