According to Osho, your worship is 'accepted' the moment you honestly expose your sins and stop bargaining for results. God's compassion is oceanic; hiding faults nourishes them, revealing them dissolves them. Prayer needs no certificate—the reward is prayer itself. Drop asking, live in gratitude, and let worship be its own bliss; then communion naturally happens.
Tell God your mistakes and stop asking for prizes; just praying with a true heart is already enough.
