The Test for Eligibity of a Brahmana - Verse 61-62

Hence a Dana (religious gift) is to be made to the guest and a Brahmacarin (celibate person) is to be fed. The Dana is to be made to one engrossed in meditation and having sympathetic feelings. In the Sraddha rite, a righteous ascetic or a Valakhilya (a mendicant who does not hoard anything) should be fed. A Vanaprastha (forest-dweller) and an Upakurvana (Brahmacarin who completes his studies and pays his teacher and is about to be a householder) is propitiated by mere worship.
