If you don’t understand a ritual, it doesn’t mean necessarily that it is meaningless. You have to remember that the most probable is that it’s deeper than your mind. So don’t confuse the practice with the code because you see only what you get. You have to go beyond the low level and to discover the depth of the ancient mind which lives in the centuries because it belongs to Time. Avoid to think only as an observer, keep in mind the depth of faith and ask to the believers what they see in the open universe which is bigger than your own reality.
