vaidyutā iva vahnayaḥ
siddha-amṛta-rasa-spṛṣṭāḥ—the demons, thus being touched by the powerful mystic nectarean liquid; vajra-sārāḥ—their bodies becoming invincible to thunderbolts; mahā-ojasaḥ—being extremely strong; uttasthuḥ—again got up; megha-dalanāḥ—that which goes through the clouds; vaidyutāḥ—lightning (which penetrates the clouds); iva—like; vahnayaḥ—fiery.
When the dead bodies of the demons came in touch with the nectar, their bodies became invincible to thunderbolts. Endowed with great strength, they got up like lightning penetrating clouds.
