pavitra पवित्र

Definition: Denotes in the Rigveda, and later, the sieve used for purifying the Soma, the only mode of purifying it certainly known to the Rigveda. It seems clearly to have been made of sheep’s wool, whether woven or plaited is not certain, for the expressions used are too vague to be decisive, though Zimmer thinks hvarāmsi points to plaiting.
