10.45.6

yas tayor ātmajaḥ kalpa ātmanā ca dhanena ca /
vṛttiṃ na dadyāt taṃ pretya sva-māṃsaṃ khādayanti hi //

6. If a son, when able-bodied, does not, by his personal effort and by his means, contribute to the comfortable living of his parents, Yama’s messengers make him eat his own flesh in hell when he departs this life.
