At the more mature stages of life, we are even able to allow the painful and the formerly excluded parts to belong to a slowly growing and unified field. This shows itself as a foundational compassion, especially toward all things different from us and those many people who don’t fit society’s standards. If you have forgiven yourself for being imperfect, you can now do it for everybody else too. If you have not forgiven yourself, I am afraid you will likely pass on your sadness, absurdity, judgment, and futility to others. What comes around goes around.
Many who are judgmental and unforgiving seem to have missed out on the joy and clarity of the first childhood simplicity, perhaps avoided the suffering of the mid-life complexity, and thus lost the great freedom and magnanimity of the second naïveté as well. We need to hold together all of the stages of life, and for some strange, wonderful reason, it all becomes quite “simple” as we approach our later years. The great irony is that we must go through a lot of complexity and disorder (another word for necessary suffering) to return to the second simplicity. We must go through the pain of disorder to grow up and switch our loyalties from self to God. Most people just try to maintain their initial “order” at all costs, even if it is killing them.
As we grow in wisdom, we realize that everything belongs and everything can be received. We see that life and death are not opposites. They do not cancel one another out; neither do goodness and badness. There is now room for everything to belong. A radical, almost nonsensical “okayness” characterizes the mature believer, which is why they are often called “holy fools.” We don’t have to deny, dismiss, defy, or ignore reality anymore. What is, is gradually okay. What is, is the greatest of teachers. At the bottom of all reality is always a deep goodness, or what Thomas Merton called “a hidden wholeness.” 
Walter Brueggemann, one of my favorite Scripture scholars, brilliantly connects the development of the Hebrew Scriptures with the development of human consciousness. 
Brueggemann says there are three major parts of the Hebrew Scriptures: the Torah, the Prophets, and the Wisdom Literature. The Torah, or the first five books, corresponds to the first half of life. This is the period in which the people of Israel were given their identity through law, tradition, structure, certitude, group ritual, clarity, and chosenness. As individuals, we each must begin with some clear structure and predictability for normal healthy development (a la Maria Montessori). That’s what parents are giving their little ones—containment, security, safety, specialness. Ideally, you first learn you are beloved by being mirrored in the loving gaze of your parents and those around you. You realize you are special and life is good—and thus you feel safe.
The second major section of the Hebrew Scriptures, the Prophets, introduces the necessary suffering, “stumbling stones,” and failures that initiate you into the second half of life. Prophetic thinking is the capacity for healthy self-criticism, the ability to recognize your own dark side. Without failure, suffering, and shadowboxing, most people (and most of religion) never move beyond narcissism and clannish thinking (egoism extended to the group). This has been most of human history up to now, which is why war has been the norm. But healthy self-criticism helps you realize you are not that good and neither is your group. It begins to break down either/or, dualistic thinking as you realize all things are both good and bad. This makes idolatry, and the delusions that go with it, impossible.
My mother could give me “prophetic criticism” and discipline me and it didn’t hurt me indefinitely because she gave me all the loving and kissing and holding in advance. I knew the beloved status first of all, and because of that I could take being criticized and told I wasn’t the center of the world.
The leaven of self-criticism, added to the certainty of your own specialness, will allow you to move to the third section of the Hebrew Scriptures: the Wisdom Literature (many of the Psalms, Ecclesiastes, the Song of Songs, and the Book of Job). Here you discover the language of mystery and paradox. This is the second half of life. You are strong enough now to hold together contradictions in yourself and others with compassion, forgiveness, and patience. You realize that your chosenness is for the sake of letting others know they are also chosen. You have moved from the Torah’s exclusivity and “separation as holiness” to inclusivity and allowing everything to belong.
Just what are those inner imperatives that rise to support us and challenge us in the journey of the second half of life? Perhaps Jung’s most compelling contribution is the idea of individuation, that is, the lifelong project of becoming more nearly the whole person we were meant to be—what [God] intended, not the parents, or the tribe, or, especially, the easily intimidated or inflated ego.
While revering the mystery of others, our individuation summons each of us to stand in the presence of our own mystery, and become more fully responsible for who we are in this journey we call our life. So often the idea of individuation has been confused with self-indulgence or mere individualism, but what individuation more often asks of us is the surrender of the ego’s agenda of security and emotional reinforcement, in favor of humbling service to the soul’s intent. . . .
The agenda of the first half of life is predominantly . . . framed as “How can I enter this world, separate from my parents, create relationships, career, social identity?” Or put another way: “What does the world ask of me, and what resources can I muster to meet its demands?” But in the second half of life . . . the agenda shifts to reframing our personal experience in the larger order of things, and the questions change. “What does the soul ask of me?” “What does it mean that I am here?” “Who am I apart from my roles, apart from my history?” . . . If the agenda of the first half of life is social, meeting the demands and expectations our milieu asks of us, then the questions of the second half of life are spiritual, addressing the larger issue of meaning.
The psychology of the first half of life is driven by the fantasy of acquisition: gaining ego strength to deal with separation, separating from the overt domination of parents, acquiring a standing in the world. . . . But then the second half of life asks of us, and ultimately demands, relinquishment—relinquishment of identification with property, roles, status, provisional identities—and the embrace of other, inwardly confirmed values.
After he retired, my father cried in my arms and said, “I don’t know who I am now. I don’t know who I am. . . . Pray with me, pray with me.” Here I was a grown-up man, a priest, supposed to be strong for my father. I didn’t know how to do it. I guess I said the appropriate priestly words. But I didn’t know how to guide him into the second half of life, and he was begging for a guide.
The church wasn’t much of a guide in such things. The common sermon was on the evil of abortion. My mom in her 70s would come home and say, “Why does the priest keep telling us the same thing? I can’t have babies anymore!” That’s what happens when the Church doesn’t grow up or support its growing members. We focus on something that’s quantifiable and seemingly clear and has no subtlety to it. It’s mostly black and white thinking, usually about individual body-based sins. We know who the sinners are, and we know who the saints are, and we don’t have to struggle with the mixed blessing that every human being is. We’re all mixed blessings and partly sinners, and we always will be. But this wisdom only comes later, when we’ve learned to listen to the different voices that guide us in the second half of life.
These deeper voices will sound like risk, trust, surrender, uncommon sense, destiny, love. They will be the voices of an intimate stranger, a voice that’s from somewhere else, and yet it’s my deepest self at the same time. It’s the still, small voice that the prophet Elijah slowly but surely learned to hear (see 1 Kings 19:11-13).
In the Franciscan reading of the Gospel, there is no reason to be religious or to “serve” God except “to love greatly the One who has loved us greatly,” as Saint Francis said.  Religion is not about heroic will power or winning or being right. This has been a counterfeit for holiness in much of Christian history.
.. While the Ten Commandments are about creating social order (a good thing), the eight Beatitudes of Jesus are all about incorporating what seems like disorder, a very different level of consciousness. With the Beatitudes, there is no social or ego payoff for the false self. Obeying the Commandments can appeal to our egotistic consciousness and our need to be “right” or better than others.
.. Obedience to the Ten Commandments does give us the necessary impulse control and containment we need to get started, which is foundational to the first half of life. “I have kept all these from my youth,” the rich young man says, before he then refuses to go further (Mark 10:22).
The Beatitudes, however, reveal a world of pure grace and abundance, or what Spiral Dynamics and Integral Theory would call the second tier of consciousness and what I call second-half-of-life spirituality.
His actual life and practice show how he deliberately undercut the entire “honor/shame system” on which so much of culture, violence, false self-esteem, and even many of the ministrations of church depends. Doing anything and everything solely for God is certainly the most purifying plan for happiness I can imagine. It changes the entire nature of human interaction and eliminates most conflict.
