Krish44 brilliant answer.
I repeat I like Krish44 answer, i will tell my friend. He is about to get married, and you know he is already neurotic and such beliefs will only make him worse, at-least he will know the underlying concept and will decide what he wants to do with this impending marriage.
Krish44 Ji, to my knowledge (I am from a modern city - atleast from this BELIEF point of view ) I never heard of such things in the past few decades... I am self-realised, meaning (at-least my meaning of SELF-REALISATION, for a practical 2nd decade of this 2nd MILLENNIUM life) will adapt to changes in life much better than my neurotic friend.
Sangom Ji, I will not go into your clarification. I am already scared of your questions and on top of that there is something orange in the BOTTOM of your POST, which i don't understand. Please excuse me. To be honest I FEEL LIKE GETTING DRAGGED INTO SOME BIG DIRTY POOL OF CONFUSED NOMENCLATURE AND THE ANANTHA NAG IS ABOUT TO EAT ME ( actually it has already bitten my feet )
I will start another thread on discrimination...
