Mahabharat
स्वान्यड्रान्यभिसंक्षिप्य निष्क्रान्तो बलनाशन: । ततः प्रभूृति लोकस्य जृम्भिका प्राणसंश्रिता ॥ ५-९-५४ ॥
- the slayer of the Asura, Bala contracted the different parts of his body, and came out from within Vritra's mouth. And thenceforth the yawn attaches itself to the living breath of animated beings in three worlds.
