sa mahāsattvasannādaḥ śailapīḍānimittajaḥ| pṛthivīṃ pūrayāmāsa diśaścopavanāni ca
Due to the crushing of the mountain, a loud noise of the various creatures shot up filling the earth in all directions and groves around.
— M.N. Dutt (1891)
The sound of the creatures' cries fills the earth and the groves around. The scale of the sound matches the scale of the event — this is not a private departure but a cosmic occurrence. The entire world takes note of Hanuman's leap.
