In regions which have not been forbidden, silent recitation of sacred Mantras, homa round fasts, knowledge of soul, sacred rivers, regions inhabited by men devoted to pious acts,-these have been laid down as purifying acts and objects. Certain mountains also are purifying, as also the eating of gold and bathing in waters into which have been washed gems and precious stones.
अनादेशे जपो होम उपवासस्तथैव च। आत्मज्ञानं पुण्यनद्यो यत्र प्रायश्च तत्पराः॥ अनादिष्टं तथैतानि पुण्यानि धरणीभृतः। सुवर्णप्राशनमपि रत्नादिस्नानमेव च॥
