Greetings friends. I have heard about the "tulpa" and thought forms, and the information usually describes the user's ability of using the mind to create and command "incorporeal" entities by the methods like vizualization. I understand and believe this. What I don't understand, is how is it possible? By saying this, I mean, what is the functionality of this process of creating this entities, or for example, how come can one make and bring to existence this type of beings, since this process only takes place on the brain. How can an internal process affect external objects? Is the brain somehow connected to objects and solids thru a unvisible force that connects all things? This is what I would like to find out, and if there is any of you that happens to know the answers to my questions, please let me know, because this topic is very interesting. I would thank you very much.
