Re: Which branch of Aikido emphasizes Spirituality?
How do you define spiritual content? Meditation? Chanting? Scheduled lectures? In terms of technical emphasis within the techniques?
There are aikido teachers who are ordained priests. There are aikido teachers with extensive academic credentials in eastern religions, philosophy, and related fields. There are dojos with Buddhist and/or Shinto altars on the premises. There are dojos that schedule meditation retreats, and there are dojos that schedule rock climbing trips.
What are you looking for?
