The real difference between yoga and religion is this: Religion says believe, do not doubt, often citing the word of God and promises of an eternal afterlife, reciting dogma (unsubstantiated pre-modern myths), while yoga only points the way and urges its students to practice and experience for themselves. In this way yoga is very scientific in its approach to self-knowledge, transcendence and enlightenment. Its message is: Try the practice for yourself and only then can you truly believe.
