Is it necessary to believe in something, such as a god, in order to be spiritual? That is, does spirituality require belief? Why or why not?
For the purposes of this thread, let's define "spirituality" as "the extent and manner in which a person deals with or copes with their psychological self." A person who was relatively skillful at dealing with their psychological self would thus be considered relatively spiritual.
"Psychological self" here means the self, the "I", the ego, the consciousness, or whatever you want to call those things that we identify as being us. For instance, I might think of myself as being the thoughts that run through my head. Or I might think of myself as being my awareness or consciousness. Or I might think of myself as being to some extent, or in some fashion, a particular clothing style that I identify myself with -- e.g. "That's my look." or "That's me." Or perhaps I think of myself as being in some way the things I legally own. What I think of as "me" is potentially all but unlimited. The manner and extent to which I deal with or cope with the fact of my having a psychological self constitutes my spirituality.
I would say that belief in deities or anything exoteric to the body wouldn't be required.
Belief internally(spiritually), within oneself would make more sense. Belief that there is a latent power/energy/source within that can heal, teach, expand. Believing in that power source vested within someone to change, overcome, defeat their inner enemies that take away peace and joy.
If someone were psychogically suffering in any way, it would require belief and faith within oneself that there is an escape from such psychological suffering. The sea of consciousness has many forms, there are more and more and more and more and infinite sides to the sea. Some seas are rough and painful, some are calm and blissful. While in the rough and painful, believing and hoping that there is another side of the sea. . which there always is. Belief that there is even something to see(be aware of) beyond what we can see(are currently aware of.)
We are constantly, albeit indirectly usually, always asking others to have faith and believe by our reasoning together and the planting of seeds in each other's minds. When someone asks another, what would change your mind about something? In order for someone to change their mind about something, they would initially have to believe and have faith 1)that they can change, 2)that there even is something to change for, and 3)in the reason to change.
Belief within becomes knowing/direct experience, continuous belief within becomes the expansion of knowing.
Ie: person X, "I'm a fundamental Zionist."
Person Y, "That's stupid and dogmatic."
Person X, "I would have to believe that is stupid and dogmatic in order to change."
Person Y, "Belief is for the delusional."
Person X, "But I would have to believe your way is better."
Person X, "I suffer from depression."
Person Y, "Do you believe and have faith that you can overcome depression?"
Person X, "Belief is for the delusional."
Person Y, "You should try to have faith, you can overcome."
Person X, "Faith in what, your deity?"
Person Y, "No, faith there is a power within you to overcome."
Person X, "I will do such and such tomorrow at the lab."
Person X without being aware, "I have blind faith and belief that I will do such and such tomorrow at the lab for I do not know the future."
