SB 3.20.37
iti sayantanim sandhyam
asurah pramadayatim
pralobhayantim jagrhur
matva mudha-dhiyah striyam
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
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.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
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.
