One thing that tends to cross my mind is whether God is real, or yet what God would want from me. I tend to believe in Him, though not quite in an Abrahamic nor Hindi/Sanskrit way. I believe that God is real in the mind of believers and not real in the mind of non-believers.
How can God be real in some people, but not in others? Simple. When one is praying to or talking to God, the areas of the brain that deal with communication light up in the same way it does when an objective, concrete and real person communicates with you, a reputable scientific study noted.
Why would anyone choose to believe in God? What is in it for believers? Well, it's best to ask what is in it for God, because you are inviting Him into your own mind, and He has to be treated with respect, as He is very important and loves all of us who truly believe!
God gives me a sense of relief, or of belonging. He is the warmth of the sun, the calmness of the moon, and the stars in our eyes. It's like I'm never alone, no matter how scared I may be, or how lonely I get. God listens to our prayers, and is eternally patient. He listens more than he talks, but we should remember to listen to Him too!
Dudeism itself is non-theist, but as stated on the Dudeism website, it's ok to believe in a higher power, man(even though God doesn't have to be make, as God can be female, or maybe both, or maybe even genderless, it's up to you).
