I saw the thread about meditation and it reminded me of a question I've been meaning to post regarding human psyche and neurobiology.

I've been considering creating a Tulpa. For those who don't know; a Tulpa is an artificial being you meditate into reality. For those of you that aren't from /X/ it means meditating yourself into a form of benign schizophrenia.
I've been considering the cost/benefit of attempting to create a separate mental entity from my own subjective self that I can interact with. The idea would be to visualize and attempt to create an entity with competencies I lack or possess to no significant degree. The aim would be to have a mental partner to cooperate with and seek counsel from.

Anyone who knows enough neurobiology to add interesting information to this?
It is literally the act of inflicting myself with multiple personality disorders. What are the pep's? What are the con's? Is it even worth the time and energy required to execute it in a way that minimises the risk of mental breakdown?
