Bhagavad Gita 18.77
As I recall again and again the exceeding beauty of the Lord, I am filled with amazement and joy.
तच्च संस्मृत्य संस्मृत्य रूपमत्यद्भुतं हरेः।
विस्मयो मे महान् राजन् हृष्यामि च पुनः पुनः॥tacca saṃsmṛtya saṃsmṛtya rūpamatyadbhutaṃ hareḥ|
vismayo me mahān rājan hṛṣyāmi ca punaḥ punaḥ||
