In plain words
Ajñāna, not knowing oneself, lets the universe arise; Jñāna, self-knowledge, brings it to rest. This holds for every Jīva up to Hiraṇyagarbha, the Śruti says. When one awakens, the world is dissolved into Brahman; while ignorance rules, Brahman is mistaken for the world—like silver seen on a shell, and the shell then understood only through the imagined silver.
Close to the Sanskrit
Ajñāna, ignorance of oneself, and Jñāna, self-knowledge, are the causes common to the universe's arising and dissolution among all Jīvas up to Hiraṇyagarbha; so the Śruti declares. At one's awakening the universe is offered into Brahman; under ignorance Brahman is in turn offered into the world—just as silver is projected on a shell and the substratum, the shell, is taken for silver through reciprocal delusion.
