7.15.36

yaḥ pravrajya gṛhāt pūrvaṃ trivargāvapanāt punaḥ /
yadi seveta tān bhikṣuḥ sa vai vāntāśyapatrapaḥ //

36. He who, having first renounced the house, (householder's life) the field of Dharma, Artha, and Kama, again takes to their enjoyment is verily a shameless ascetic who swallows (may be compared to one that swallows) the food he had vomited.
