A golden vessel which shows no stains, becomes pure with water alone, likewise what is produced in water (as shells and coral), what is made of stone, and a silver (vessel) not enchased.
From the union of water and fire arose the glittering gold and silver; those two, therefore, are best purified by (the elements) from which they sprang.
द्रवाणां चैव सर्वेषां शुद्धिरुत्पवनं स्मृतम् । प्रोक्षणं संहतानां च दारवाणां च तक्षणम् ॥ ११५ ॥
The purification prescribed for all (sorts of) liquids is by passing two blades of Kusa grass through them, for solid things by sprinkling (them with water), for (objects) made of wood by planing them.
