In plain words

The mind went out. Having stayed away a year, it came back and said, "How could you live without me?" They said, "As simpletons live, not knowing with the mind but breathing with the breath, speaking with speech, seeing with the eye, hearing with the ear, begetting with the seed — so we lived." And the mind entered in again.
