With religion and spirituality such a deep and essential part of daily life in Bali, it will be a process of discovery, listening, study  to really understand it. I spent the last couple hours reading Bali history, reading about Bali temples and yet some simple instructions from our driver and friend, Made, I think were more helpful than all the rest.
His instructions for participating in the ceremony were to relax, let go, purify, be at peace.
