शङ्खचूडवधे शिवोपदेशो नामैकत्रिंशोऽध्यायः
Lord Shiva’s advice at the killing of Shankhachuda – Chapter 31
कैलासवासिनं रुद्रं मद्रुपं पुर्णमुत्तमम् |
देवकार्यार्थमद्भुतं पृथगाकृतिधारिणम् || 39 ||
My form as Rudra, residing in Kailasha is the complete and the best form, which for (various tasks of) Devas takes on different shapes (forms/bodies).
आवयोर्भेदकर्ता यः स नरो नरकं व्रजेत् |
इहापि प्राप्नुयात्कष्टं पुत्रपौत्रविवर्जितः || 42 ||
A man who makes a distinction between two of us goes to hell. He also gets suffering here (on earth), and will not have sons or grandsons.
