Re: Religion and Aikido
I agree with you, however I would choose not to use the word doctrine, but words such as "history", lessons, experiences. We cannot throw away those things that are vital to our humanity and our growth.
We are but what our forefathers left for us, we evolve and grow based on those experiences.
as you state, we must interpret them for ourselves and look introspectively to find the truth and meaning that allows us to escape the confusion, road blocks, assumptions, emotions, and paradigms that get in the way of us discovering "the truth".
I agree just simply don't like the word doctrine as it has so many negative conotations with it.
