Mbh 13.126.7

"'"Dharma said, 'The offerings made in all rites in honour of the deities and in those in honour of the Pitris should never be given away to a Brahmana that has accepted service under the king, or that rings the bell or attends to subsidiary duties in acts of worship or at Sraddhas, or that keeps kine, or that is engaged in trade, or that follows some art as a profession, or that is an actor, or that quarrels with friends or that is destitute of Vedic studies, or that marries a Sudra woman[551]. The performer of the Sraddha who gives away such offerings unto such a Brahmana falls away from prosperity and multiplies not his race. He fails, again, to gratify his Pitris by doing such an act. From the house of that person whence a guest returns unsatisfied, the Pitris, the deities, and the sacred fires, all return disappointed in consequence of such treatment of the guest. That man who does not discharge the duties of hospitality towards the guest arrived at his abode, comes to be regarded as equally sinful with those that are slayers of women or of kine, that are ungrateful towards benefactors, that are slayers of Brahmanas, or that are violators of the beds of their preceptors.'
