One should never eat any food in which he may find out a hair. Nor should one eat at the Shraddha of an enemy. One should eat silently; one should never eat without covering his body with an upper garment, and without sitting down.
वालेन तु न भुञ्जीत परश्राद्धं तथैव च॥ वाग्यतो नैकवस्त्रश्च नासंविष्टः कदाचन।
