The Rudrākṣas of the size of an Emblic myrobalan and those of lighter weight but depressed with thorns, those eaten by worms or without holes and those characterized by other defects shall not be worn by those wishing for auspicious results. They shall avoid small ones of the size of gram. O Umā, Rudrākṣa is an auspicious complement to my phallic image. The small one is always praiseworthy.
If any one wears it during the day he is freed from sins committed during the night; if he wears it during the night he is freed from the sins committed during the day. Similar is the result with its wearing during morning, midday or evening.
रुद्रा क्षमेकं शिरसा बिभर्ति तथा त्रिपुण्ड्रं च ललाटमध्ये । पंचाक्षरं ये हि जपंति मंत्रं पूज्या भवद्भिः खलु ते हि साधवः 1.25.५० ।
He who wears a single Rudraksha bead on his head, and also bears the Tripundra (three vertical lines of ash) on his forehead, and chants the Panchakshara mantra (the five-syllable mantra of Shiva), is indeed revered by you, and such a person is truly a pious soul (Sādhu).
