Since neither Lord Śiva nor you nor I could ascertain the limits of spiritual happiness, how can other demigods know it? And because all of us are bewildered by the illusory, external energy of the Supreme Lord, we can see only this manifested cosmos according to our individual ability.
Srimad Bhagavata Purana
श्रीमद्भागवतमहापुराणम्
मूल श्लोकः
यस्यावतारकर्माणि गायन्ति ह्यस्मदादयः । न यं विदन्ति तत्त्वेन तस्मै भगवते नमः
yasyāvatārakarmāṇi gāyanti hyasmadādayaḥ | na yaṃ vidanti tattvena tasmai bhagavate namaḥ
