In very real ways, soul, consciousness, love, and the Holy Spirit are one and the same. Each of these point to something that is larger than the individual, shared with God, ubiquitous, and even eternal—and then revealed through us! Holiness does not mean people are psychologically or morally perfect (a common confusion), but that they are capable of seeing and enjoying things in a much more “whole” and compassionate way, even if they sometimes fail at it themselves. 
.. Our effort is not a self-conscious striving to fill ourselves with the important Christian virtues; it is more getting out of the way and allowing [Christ’s] Spirit to transform all our activities. Christ will do the rest. His Spirit has joined ours and will never abandon us.
The Holy Spirit is the love relationship between the Father and the Son. It is this relationship itself that is gratuitously given to us! Or better, we are included inside this universal love. This is salvation in one wonderful snapshot
Jesuit Richard Hauser (1937–2018), who focused much of his teaching and writing on the Holy Spirit, saw that the indwelling Spirit leads to union and love:
This love has as its object God, as well as other people. Christian theological tradition has most often seen the Holy Spirit in the Trinity as the bond of love between the Father and the Son. . . . The primary effect of the Spirit acting in people . . . will be love, both for one another and for God. . . .
God’s Spirit joins our spirit; it does not replace it. The good acts we perform are truly our acts, not simply acts of the Holy Spirit in us. The deepest part of the self is the spiritual dimension. From the center flows all our freedom and love; at this level we remain free to choose to move or not to move with the Spirit. The Holy Spirit is indeed active in us at all times drawing us toward greater love and service of God and others, but the Spirit does not control our response. That flows from our freedom. 
This loving relationship shows itself in myriad forms, such as the endless diversity of insects and wildflowers, culture and art, medicine and science. Each manifestation expresses God’s endless desire to create new forms of life and externalized love. All things good, true, and beautiful are already baptized in the one, same Spirit. (Read Ephesians 4:4-7 anew!)
The Holy Spirit shows up as the central and healing power of absolute newness and healing in our relationship with everything else. Anglican mystic Evelyn Underhill (1875–1941) defined mysticism as “the art of union with Reality.”  The Spirit is the artist painting this union through us!
The Spirit’s work is helping us stay in relationship and building connection. The Spirit warms, softens, mends, and renews all the broken, cold places in and between things. Invisible but powerful, willing to be anonymous, the Spirit does not care who gets the credit for the wind from nowhere, the living water that we take for granted, or the bush that always burns and is never consumed.
As St. Francis is often quoted as saying, “You must preach the Gospel at all times, and when necessary use words.” This demands no “belief” or theology whatsoever, but only eyes wide open.
.. In the great basilica in Assisi where Francis is buried, there is a wonderful bronze sculpture of Francis inviting the Holy Spirit. Instead of looking upward as is usual, he gazes reverently and longingly downward—into the earth—where the Spirit is enmeshed. Francis understood that the Holy Spirit had in fact descended; she is forever and first of all here! There are artists who inherently understand incarnation.
St. Thomas Aquinas often wrote, “If something is true, no matter who said it, it is always from the Holy Spirit.”
Hildegard says, “O Holy Spirit, you are the mighty way in which every thing that is in the heavens, on the earth, and under the earth, is penetrated with connectedness, penetrated with relatedness.”
