According to Osho, vows, rituals, or particular actions are irrelevant; only awareness bears fruit. Whether one is fasting or feasting, worshipping or even stealing, if awareness dawns in the doing, the same transformation arises. The vow-bound and the vowless are equal before consciousness: with awareness, both flower; without it, both are barren. Wake up where you are, and fruition follows.
Rules don’t change you; being fully aware of whatever you’re doing does—and it works the same for people with or without vows.
