। ॥ २१ ॥
In plain words
Above the six lotuses rests your subtle Kalā, a power fine as lightning and made of sun, moon, and fire. Great souls who see you in that vast lotus-forest with minds cleansed of impurity and Māyā—the power of obscuration—are swept into a wave of highest joy.
Close to the Sanskrit
Slender as a streak of lightning, composed of sun, moon, and fire, your Kalā—your radiant power—rests above all six lotuses. In the great lotus-forest, the great ones behold you with minds in which impurity and Māyā have been crushed, and they bear a wave of supreme delight.
