Bhagavad Gita Chapter 11, Verse 1

अर्जुन उवाच | मदनुग्रहाय परमं गुह्यमध्यात्मसंज्ञितम् | यत्त्वयोक्तं वचस्तेन मोहोऽयं विगतो मम ||

arjuna uvāca mad-anugrahāya paramaṁ guhyam adhyātma-saṁjñitam yat tvayoktaṁ vacas tena moho 'yaṁ vigato mama

Arjuna said: By Your grace, the supreme secret concerning the Self (adhyātma) that You have spoken to me has destroyed my delusion.

Arjuna acknowledges Krishna's grace (anugrahāya) and expresses gratitude. 'Paramaṁ guhyam adhyātma-saṁjñitam'—the supreme secret (paramaṁ guhyam) concerning the Self (adhyātma) that Krishna has revealed. 'Yat tvayoktaṁ vacaḥ'—the words You have spoken. 'Tena moho 'yaṁ vigato mama'—by that, my delusion (mohaḥ) has been destroyed (vigataḥ). This verse marks the transition from Chapter 10's teachings about divine glories to Chapter 11's vision of the universal form. Arjuna's confusion is gone—he understands Krishna's supreme nature. Now he's ready for the next revelation: seeing the cosmic form. This sets up his request in the next verses.
