Honestly, no. We learn from others and ourselves in relation to our outside environment and things we picked up (to generalize) that helped shape our internal environment. It's beneficial to ask questions because it does help you know more about yourself.
Questions such as what is god or even why did you yell at me would I would think give a sense of how one relates to god and how to improve his or her character.
I think this is more religious differences than anything else, to tell you honestly. For example, some people believe when you drop the ego and identification with form and substance (any good/bad) then there's just a blank state of awareness of self/soul/god. Some find and experience god (rather than as god) in communion with other people. So they self-reflect and pray alone (thereby observe themselves in relation to god) in a relationship with other worshipers.
When I sit and meditate in the evening with my journals, pens, and notebooks, that's fine and all but I can't do anything with it without physical discovery and interaction with my environment and people. What is the use of observation or looking in the mirror thinking the mirror reflection is your inner self when that reflection only exist because of the person looking into it, not exist on its own accord.
So, you can learn a lot of yourself from your reflection (observation). Just, in my opinion, don't mistake the reflection for yourself.
Instead of just observing yourself, be yourself.
On a side note. Couple years ago I was listening to talk about habits. The author mentioned motivation comes from action rather than action comes from motivation. Our motivation is temporal. We can only "sit" for certain amount of time. However, if we start building discipline through action via consistency, the motivation would come as a result of action not the cause of it.
Observing yourself is fine. I just find if you be yourself through action, you'd see clearer just as someone can look up at the sky and imagine themselves connected to the universe but once they use a telescope, well, you can see the beauty of it as well.
What would happen if a Religious/ spiritual person stopped asking questions, and only observed everything around and within him/her/it self?
Is it even possible to be fully neutral and only observe?
I don't see either as more spiritual than the other, but I guess it would depend on the questions. What questions would the religious or spiritual person would stop asking?
