I am interested in pursuing a Masters/PhD program in the US but I do not have a bachelor’s degree
Your experience is not in science, why would you have equivalence in any science related bachelor degree? 

I am completely sure that your experience on religion/spirituality/self-help/alternative therapies/human interactions will not guarantee equivalence in psychology or neuroscience related degrees. The knowledge expected from a person holding one of these degrees is completely different.

However, instead of pursuing a PhD why not engage in a bachelor course? The bachelor will give to you many tools of which you will need to work in a PhD.
