There are arcana to be discovered in every tradition. You hit upon an arcana when you discover it to be a causative principle. The arcana would be what was referred to by Socrates when he referred to “prefect forms”. If you have the intention of peace, then your meditation is the arcana that leads to peace. If you have the intention of atonement, then your prayer is the arcana that leads to communion. If you have the attention of reverence, then ceremonial dance can move the spirits just as well as it moves your flesh and blood, but arcana can need refinement. Imperfect understanding leads to imperfect results.
In your spiritual/magickal practice consider breaking your tradition down into its elements, its arcana. Then like an artist considering the elements of their art, free yourself to personalize your relationship to it. Your work will have much more power/beauty/efficacy.
