If you need real emotional processing, that needs to be done in an space or heat opening empathy..take mescaline..
Ayahuasca and mushrooms can do it also..and they are my preferred routes..but thi is what I would suggest..do some work with ayahuasca and/or mushrooms..and follow up with mescaline cacti..Im very serious about the mescaline..you just have to take mescaline to understand..with mushrooms and ayahuasca you can gain some feel for what the other is like..but mescaline works on a very very different level for me personally. The only thing that was similar so far has been MDMA, but there is still somethign that sets mescaline apart IMO..MDMA really has my respect though when used properly and sparingly for psychological healing of repressed emotion based states of mind.
And yeah....Red caapi...caapi to me also has a very MDMAish quality in a sense, must be the seratonin flow..but lacking the stimulation and other side effects..
