According to Osho, devotion to Krishna has no test or gradation—love either is or is not, and when it is, it is already total. Like pain, it proves itself from within; no external criterion is needed. Stop measuring; become loving here and now—toward people, nature, the tangible—and the invisible Krishna shines through. Seeking a 'highest' only betrays absence; real bhakti is self-evident, indivisible presence.
You can’t test true love for Krishna; if it’s real, you feel it inside and it makes you kind to everything around you.
