SB 6.18.48
napsu snayan na kupyeta
na sambhaseta durjanaih
na vasitadhauta-vasah
srajam ca vidhrtam kvacit
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Kasyapa Muni continued: My dear gentle wife, never enter the water while bathing, never be angry, and do not even speak or associate with wicked people. Never wear clothes that have not been properly washed, and do not put on a garland that has already been worn.
