If there is one thing useful that I would have to pick that Freud gave us, it is the idea of id, superego and ego. The id is what you want to do. The superego is what society wants you to do, and the ego is what you do in light of your id and superego. Something is wrong if you let either the id or superego do all the thinking. It is best to take the balance with the ego.
Japanese culture has this built-in to their thinking with the concept of in-group/out-group. We must always think of ourselves not as just mere individuals but also in relation to society.
Or this is similar to Schopenhauer’s idea of will and representation. We are individuals in charge and control of our self (will) to be contrasted to things outside beyond our control (representation).
While abstraction is something we humans are good at it is dangerous to let it take over without a return to the real world or reality. No matter what the world is where we exist and only exist. Any other thought is wrong.
I am not against Jodo Shin sect at all but rather misinterpretations by people of what its original founders had intended. Like all societies and their religions there will be radical offshoots. Is it okay to start a prostitution house just because you have a sympathetic ear?
