7.4.24

तेषामाविरभूद्वाणी अरूपा मेघनि:स्वना । सन्नादयन्ती ककुभ: साधूनामभयङ्करी ॥ २४ ॥

tesam avirabhud vani arupa megha-nihsvana sannadayanti kakubhah sadhunam abhayankari

tesam
in front of all of them
avirabhut
appeared
vani
a voice
arupa
without a form
megha-nihsvana
resounding like the sound of a cloud
sannadayanti
causing to vibrate
kakubhah
all directions
sadhunam
of the saintly persons
abhayankari
driving away the fearful situation.

Then there appeared before them a transcendental sound vibration, emanating from a personality not visible to material eyes. The voice was as grave as the sound of a cloud, and it was very encouraging, driving away all fear.
