Adi Shankarar in argument with Mandanamisrar's wife

Shankaracharya and Mandanamisrar's wife were on an argument about "meemaamsam". If Shankaracharya wins the argument then Mandanamisrar should take sannyas, on the other hand if Shankarar loses then he has to give up his sannyas. Eventually Shankarar wins the argument and Mandanamisrar follows him as a sannyasin.

Faithfulness in marriage means fidelity and much more. It includes mental faithfulness, non-flirtatiousness and modesty toward the opposite sex. A married man, for instance, should not hire a secretary who is more magnetic or more beautiful than his wife.
