Real religious principles are enacted by the Supreme Personality of Godhead. Although fully situated in the mode of goodness, even the great ṛṣis who occupy the topmost planets cannot ascertain the real religious principles, nor can the demigods or the leaders of Siddhaloka, to say nothing of the asuras, ordinary human beings, Vidyādharas and Cāraṇas.
Srimad Bhagavata Purana
श्रीमद्भागवतमहापुराणम्
मूल श्लोकः
धर्मं तु साक्षाद्भगवत्प्रणीतं न वै विदुरृषयो नापि देवाः । न सिद्धमुख्या असुरा मनुष्याः कुतश्च विद्याधरचारणादयः
dharmaṃ tu sākṣādbhagavatpraṇītaṃ na vai vidurṛṣayo nāpi devāḥ | na siddhamukhyā asurā manuṣyāḥ kutaśca vidyādharacāraṇādayaḥ
