apasavyaṃ na gacchec ca devāgāracatuṣpathān
māṅgalyapūjyāṃś ca tato viparītān na dakṣiṇam //

"When a man has bathed, he must not wipe his limbs with a towel nor with his hands, nor shake his hair, nor rinse his mouth before he has risen. Let him not (when sitting) put one foot over another, nor stretch forth his foot, in the presence of a superior, but sit with modesty in the posture called Vírásana (or on his knees). He must never pass round a temple upon his left hand, nor perform the ceremony of circumambulating any venerable object in the reverse direction. A decent man will not spit, nor eject any impurity, in front of the moon, fire, the sun, water, wind, or any respectable person; nor will he void urine standing, nor upon the highway: he will never step over phlegm, ordure, urine, or blood; nor is the expectoration of the mucus of the throat allowable at the time of eating, offering sacrifices or oblations, or repeating prayers, or in the presence of a respectable person.
