bibhryad yady asau vasah
tyaktam na lingad dandader
anyat kiñcid anapadi
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
A person in the renounced order of life may try to avoid even a dress to cover himself. If he wears anything at all, it should be only a loincloth, and when there is no necessity, a sannyasi should not even accept a danda. A sannyasi should avoid carrying anything but a danda and kamandalu.
