..Daanam Pratigraham Chaiva Brahmanaanaamakalpayaat
Here, only Brahmana is entitled for Pratigrham-acceptance of Dhaana(Donation) from others, (though in tradition it is forbidden to receive by demand) reason being the observance of Gayathri Japa in routine that would protect from any sin incurred thru receiving.
Another saying in similar sense (heard of) is
Yejamana krutham paapam Anna roopena thishtathi
(Sin done by the Master , is imbibed in the food offered by that Master)
Any scriptural reference available for the above verse ?
Does any other veritable scriptural reference convey a similar sense?
