aliṅgī liṅgiveṣeṇa yo vṛttim upajīvati
sa liṅgināṃ haraty enas tiryagyonau prajāyate //

One who gains his subsistence by wearing (a lock on the crown of the head or other) distinguishing marks of a caste or religious order, to which he does not belong, takes upon himself the (consequences of the) sins committed by those who have a right to those marks, and enters in a future birth the womb of an animal.
