Sūta said: On seeing them (the ruthless Yakṣas), the intelligent self-possessed lord became displeased. Due to this displeasure, his hairs became shivered. Those shivered hairs moved up and ascended again and again. Those hairs that dropped off from the head moved and crawled up. They are considered Vyāla, because they were (originally) Bālas or Vālas (hairs). Since they drooped off (Hīmtvāt) they are remembered Ahis (serpents).
