Dakshinamurthy Stotram 9

That sphuraṇaṃ, consciousness manifests as the whole world, lending its sentiency to all, making the insentient (asat) appear sentient (sat). To understand this, Swaminiji explains the manifest chaitanya in three ways as the adhiṣṭhāna-chaitanya, vrtti-gata-chaitanya, and sākṣī-gata-chaitanya. The truth of the chaitanya, being non-dually one.
