इति सायन्तनीं सन्ध्याम् असुराः प्रमदायतीम् ।
प्रलोभयन्तीं जगृहुर् मत्वा मूढधियः स्त्रियम् ॥ ३७ ॥
matva mudha-dhiyah striyam
iti-in this way; sayantanim-the evening; sandhyam-twilight; asurah-the demons; pramadayatim-behaving like a wanton woman; pralobhayantim-alluring; jagrhuh-seized; matva-thinking to be; mudha-dhiyah-unintelligent; striyam-a woman.
The asuras, clouded in their understanding, took the evening twilight to be a beautiful woman showing herself in her alluring form, and they seized her.
The asuras are described here as mudha-dhiyah, meaning that they are captivated by ignorance, just like the ass. The demons were captivated by the false glaring beauty of this material form, and thus they embraced her.
