According to Osho, awakening happens in only two ways: gradual and sudden. Gradual paths (e.g., vipassana) unfold bit by bit so subtly you may not notice until a master confirms it—like a frog in slowly heating water. Sudden paths (e.g., Zen koans) ripen invisibly, then strike in an instant, birthing dramatic, story-worthy breakthroughs.
Waking up can be slow like a sunrise you barely notice, or sudden like lightning that brightens everything at once.
