Religion and mysticism do not go hand in hand. There is no such thing.
It is not possible to be religious in any sense of the word at all that most people understand by that term and claim that one is following an esoteric mystic tradition.
If you find yourself following a religion you are not allowing the mystery of mysticism to fully unfold.
If you find yourself being "chosen by a deity" which is so popular within neopaganism, then you are not transcending certain forces.
The most important lesson with mysticism is that the religious symbols are there to point you in the true direction of spiritual truths. Not because the outer forms should be the ones worshipped.(1)
(1)This doesn't mean that there are no spiritual entities.
