Have I ever been experienced?

Do I know what I see is the truth? Or is it my reality, my opinion, a figment of my imagination or a hallucination under the influence of residual memories? Reality! reality! reality! is there anything real about reality or it is only a perspective, a subjective substitute for the truth? something that we clutch at in our fear of being lost in this world without the support of the truth that we have not yet attained to? Is it fundamentally a reaction to our insecurities? a rubber nipple to soothe the cries of the child?

What is maturity? What is experience? does experience lead to maturity when you have had it? or does it color judgement? Are they related or can maturity be attained through through other means? from books and from learning of any kind other than experience? Is maturity related to truth or the most commonly accepted form of reality?

What then is the key or keys to maturity?
