The Test for Eligibity of a Brahmana - Verse 44-49

Anything not considered properly, shall besprinkled with water. In this manner his Acamana, Vedas ( Vedic Study) Yajnas, penance, charitable gifts and vow of celibacy become fruitful. If an atheist performs holy rites without performing Acamana out of delusion, all those rites shall undoubtedly be futile. All these following should be known pure—that which is pure in words, that which is cleaned, that which is undefiled and that which is not censured. The opposite of these is impure. A hungry Brahmana should never be told—“There is nothing”. If anything is given to him after duly honouring him, it is called a sacrifice without erecting a sacrificial post. During Sraddhas, an indigent but non-begging, solitary and shy Brahmana should always be fed with food neither over-cooked nor watery. He who offers food to the low castes only, is a wicked soul, a Brahmana-slayer.
