Since our bodies are made of sattva-guṇa, we, the demigods, are internally and externally situated in goodness. All the great saints are also situated in that way. Therefore, if even we cannot understand the Supreme Personality of Godhead, what is to be said of those who are most insignificant in their bodily constitutions, being situated in the modes of passion and ignorance? How can they understand the Lord? Let us offer our respectful obeisances unto Him.
Srimad Bhagavata Purana
श्रीमद्भागवतमहापुराणम्
मूल श्लोकः
इमे वयं यत्प्रिययैव तन्वा सत्त्वेन सृष्टा बहिरन्तराविः । गतिं न सूक्ष्मामृषयश्च विद्महे कुतोऽसुराद्या इतरप्रधानाः
ime vayaṃ yatpriyayaiva tanvā sattvena sṛṣṭā bahirantarāviḥ | gatiṃ na sūkṣmāmṛṣayaśca vidmahe kuto'surādyā itarapradhānāḥ
