Śrīmad-Bhāgavatam · Text 6.12.21
Who is speaking and story frame
खल्विदं महदाश्चर्यं यद् रज:प्रकृतेस्तव ।
वासुदेवे भगवति सत्त्वात्मनि दृढा मति: ॥ २१ ॥
khalv idaṁ mahad āścaryaṁ
yad rajaḥ-prakṛtes tava
vāsudeve bhagavati
sattvātmani dṛḍhā matiḥ
O Vṛtrāsura, demons are generally conducted by the mode of passion. Therefore, what a great wonder it is that although you are a demon, you have adopted the mentality of a devotee and have fixed your mind on the Supreme Personality of Godhead, Vāsudeva, who is always situated in pure goodness.
