People equate age with maturity ("older is wiser") without reflecting on what the latter means. Physiological (bodily) maturity is usually beyond debate. Psychological and spiritual maturity are subject to major dispute.
Premise - three requisites for human maturity are (a) environmen-tal awareness, (b) reflection on the meanings of accumulated life exper-ience, and (c) the person's resident true Self consistently guiding her or his other personality subselves. Many middle-aged and older men and women who survived significant childhood neglect and trauma and have not hit personal bottom do not meet the third criteria.
Society judges them to be "mature," and they are not. One of many implications is that such wounded, unaware people expect themselves and each other to act mature (adult), and endure significant shame, guilt, and self-doubts because their thoughts, fantasies, feelings, and behaviors are often "irrational," "impulsive," and "self-centered" - i.e. "immature."
Lesson 1 in this nonprofit Web site is about assessing for and empow-ering disabled true Selves to lead and reduce psychological wounds that pro-mote psychological and spiritual immaturity.
How mature are you now - i.e. is your Self guiding your personality?
