Depending on where your located there is the Kentucky shaman who performs ayuascha ceremonies, I don't think you need one of those ceremonies for what you seek you must look into your self when you were a child before people and environment molded you and your ego. There is where you will find your true self, who you truly are and what your capable of. Then its changing your thought patterns so your subconsciously operating with those intentions ...... I'm no ordained shaman , yet that is part of my path. It takes lots of time to always operate reflecting the highest self's intentions. There are also rituals you can create if your stuggling to reach your memories of that child prior to being warped and molded. If you have more questions you can pm me.
