He has a hundred thousand eyes, he has one mouth, he has two mouths, he has three mouths, and he has many mouths. Devoting thyself to him, setting thy heart upon him, depending upon him, and accepting him as thy one refuse, do thou, O son, adore Mahadeva and then mayst thou obtain the fruition of all thy wishes."
