FAQs
Vyomāsura is a demon (son of Maya) who disguised himself as a cowherd boy and abducted many of Kṛṣṇa’s friends by using illusion, making them appear like sheep and carrying them away.
It highlights the source of his deceptive power—he was connected with strong asuric mysticism and illusion—showing how demons exploit disguise and māyā against devotees.
Not everything that looks friendly is spiritually safe; devotees should cultivate discernment, stay in good association, and take shelter of Kṛṣṇa, who ultimately protects His devotees from deception.
