Yoganidra

(“sleep of yoga”) Epithet of the Goddess
in the first episode of the Devimahatmya, the earliest and most authoritative text for the mythology of the
Goddess. In this episode, the Goddess
has lulled Vishnu into a stupor through
her power of illusion, making him
oblivious to Brahma’s cries for help
when he is menaced by the demons
Madhu and Kaitabha. Brahma is saved
when he praises the Goddess, after
which she withdraws her yogic sleep
from Vishnu; he then regains consciousness and rescues Brahma by
killing the demons.
