He thus takes the black antelope skin, with the text (Vâg. S: I, 14 a): 'Bliss-bestowing (sarman) art thou!' For karman ('hide') is the name of that (skin of the) black deer used among men, but sarman (bliss) is (that used) among the gods; and for this reason he says, 'Bliss-bestowing art thou!' He shakes it, with the text (Vâg. S. I, 14 b), 'Shaken off is the Rakshas, shaken off are the enemies!' whereby he repels from it the evil spirits, the Rakshas. He shakes it whilst holding it apart from the vessels; whereby he shakes off whatever impure matter there may have been on it.
