In plain words
Thinking of That. Speaking of That. Waking each other to That. Turning your whole life around this one thing — the wise call that the practice of Brahman.
Close to the Sanskrit
Thinking of That, speaking of That, mutually awakening one another to That, and being wholly given over to this alone — the wise know this as the practice of Brahman.
