Chapter 11, Verse 52
Part of 11: Viśhwarūp Darśhan Yog — विश्वरूपदर्शनयोगश्री भगवानुवाच सुदुर्दर्शमिदं रूपं दृष्टवानसि यन्मम। देवा अप्यस्य रूपस्य नित्यं दर्शनकाङ्क्षिणः॥
śhrī-bhagavān uvācha su-durdarśham idaṁ rūpaṁ dṛiṣhṭavān asi yan mama devā apy asya rūpasya nityaṁ darśhana-kāṅkṣhiṇaḥ
The Blessed Lord said, "It is very hard indeed to see this form of Mine which thou hast seen; even the gods are ever longing to behold it."
Lord Krishna says to Arjuna Though the gods long to behold the Cosmic Form yet they have not seen it as you have done. THey can never behold it. Just as the Chataka (a bird) longs for a drop of rain, eagerly turning its eyes towards the clouds, so also do gods yearn to behold the Cosmic Form but their wishes have not been gratified even in their dreams. Such is that marvellous vision which thou hast easily seen.
