The Supreme Lord is incapable of being worshipped by any one if he does not grant his permission to the worshipper. As for myself, it is only when I become fortunate enough to receive his permission that I succeed in worshipping him.
शक्तितश्चरितं वक्ष्ये प्रसादात् तस्य धीमतः। अप्राप्य तु ततोऽनुज्ञां न शक्यः स्तोतुमीश्वरः॥
