Instead, she hung up her love and her longing desire in this cloud of unknowing and she learned to love a thing that she might never see clearly in this life, neither by the light of understanding of her reason nor by a true feeling of sweet love in her affection. 
Clearly, the kind of love this author has in mind is of a fundamentally different quality than what we usually mean by love.
The love presented here is not affectivity or feeling, but describes what we would nowadays call nondual perception anchored in the heart. The heart’s energetic bandwidth is intimacy, the capacity to perceive things from the inside by coming into sympathetic resonance with them. In contrast to the mind, which perceives through differentiation (I am me, because I am not you), the heart takes its bearings directly from the whole (the “I” and the “you” drop out), through a process that scientists nowadays describe as “holographic resonance.”
it’s crucial that we humans make the evolutionary shift from “individuals” to “persons.”
What’s the difference?
We typically use these terms interchangeably, but for Teilhard they denote distinctly different, progressive evolutionary stages. An individual lives as an autonomous unit, subject to the old-order laws of “survival of the fittest” and planetary indifference. A person has come to understand themselves as belonging to greater relational field. They now sense their identity from a sense of wholeness in an entirely different order of coherence: a whole greater than the sum of its parts. In this greater whole both unity and differentiation are preserved; meanwhile the whole begins to be infused by a supremely personal tincture or essence. The universe is no longer random, but a system of relationships to which we all belong and are participating in!
.. As more complex forms emerged in unified units on our planet, consciousness was able to emerge with it. From this we can gather that the future of spirituality will not be found in the “enlightenment” of a select number of individuals, but will arrive through us collectively as a new “unit,” in the emergence of what we might call the mystical body of Christ.
One of the operative principles of love is that love does not rest as long as there is an inequality in love. In seeing the beloved down, the lover is moved to lift the beloved up. John says the infinite love of God will not rest until you are equal to God in love. Even though you would be absolutely nothing without God, God will not rest until you are as much God as God is God. God will not settle for a trace of inequality. In the “dark night of the soul,” we are weaned away from the ego’s finite ideas and feelings about God. We come to know that no idea about God is God. We are also weaned from our ideas about our self as being a finite, separate self apart from God.
.. Then, in some strange way, when you die, nothing will happen, because you’ve already died to the illusion that anything less than love is real; and you are aware that Infinite Love is loving you endlessly and giving itself away as your life.
Teresa asks, “Wouldn’t it be a pity not to understand ourselves?” The pity is we tend not to. Teresa is writing about healing the sorrow that arises from being exiled from our soul.
Now let us return to our beautiful and delightful castle [which is our soul] and see how we can enter it. I seem rather to be talking nonsense; for, if this castle is the soul, there can clearly be no question of our entering it [since we are the soul we are going after]. For we ourselves are the castle: and it would be absurd to tell someone to enter a room when he was in it already! But you must understand that there are many ways of “being” in a place.
.. the degree to which each of us is here right now—in terms of a deeply awake, grateful awareness of the gift and miracle of being here—varies greatly from person to person. Another way of saying it is that everyone who’s married is married. Some people are more married than others.
.. The issue is our tendency to get stuck focusing on what my father or mother, wife or ex-wife, children or friends, pastor or boss thinks of me. What if instead we could join God in knowing who God knows I am
.. How can we ponder the intimate immediacy of what matters most? How can we learn to not treat ourselves like someone we don’t want to spend time with? How can we settle into a quiet, prayerful pondering about who we deep down really are and are called to be? And how can we be more faithful to it?
