If the only prayer you ever say in your entire life is thank you, it will be enough.

The saying expresses a spirituality centered on gratitude rather than petition: to give thanks is to recognize life as gift and to align the self with the divine will. Read this way, “thank you” becomes a complete prayer because it contains humility (acknowledging dependence), attention (seeing what has been given), and love (responding with praise). Although widely attributed to the medieval Dominican mystic Meister Eckhart, the line functions more as a modern aphorism in an Eckhartian key—echoing his emphasis on inner disposition and detachment—than as a securely attested medieval formulation.
