In plain words
Consciousness joined with the aspect that says “I am” is Sakti, the power. The whole universe that shines by that power belongs to meditation on Sakti. The knowledge that has no parts is wholly without any support.
Word for word
Consciousness associated with the aspect “I exist” is Sakti. The entire universe that shines through it belongs to meditation on Sakti. Partless knowledge is indeed without any support whatsoever.
