समाः स्निग्धा दृढाः स्थूलाः कंटकैः संयुताः शुभाः । रुद्रा क्षाः कामदा देवि भुक्तिमुक्तिप्रदाः सदा २१ ।
O Goddess, Rudrākṣas of even size, glossy, firm, thick and having many thornlike protrusions yield desires and bestow worldly pleasures and salvation for ever.
क्रिमिदुष्टं छिन्नभिन्नं कंटकैर्हीनमेव च । व्रणयुक्तमवृत्तं च रुद्रा क्षान्षड्विवर्जयेत् २२ ।
Six types of Rudrākṣas shall be discarded:—that which is defiled by worms, is cut and broken, has no thornlike protrusions, has cracks and is not circular.
The wearing of Rudrākṣa is spoken of as conducive to the destruction of great sins. If eleven hundred Rudrākṣas are worn on the person, the man assumes the form of Rudra.
