It is not good for man to be alone, I would say it is against human nature to be alone. To be in communion with others reflects the image of the Trinity. Not only, it makes me journey with God in the neighbor, a necessity in order to actualize the gospel. "Love of God" is an illusion without love of neighbor. Not only, with the neighbor one could see with the "third eye" about one's defects and mistakes.
Perfection could not be attained alone. Perfection, which is an attempt to be like the most perfect Being needs to know the nature of God. God is Trinity since God is love. Perfection then necessarily entails communion of love with one's neighbor. To be humble in fornt of the neighbor: to see "God" in the neighbor; "to listen what the neighbor does not say."
True communion leads me to realize that alone, it is impossible to be true to one's nature as an image of God who is a communion of the three divine Persons. It makes me faithful to the image and likeness of God. My
identity is to be with a "thou". With the neighbor I could have a spiritual mirror to which I could see, through true communion, my defects and therefore the possibility to improve.
I thank God for giving me the gifts of true and authentic persons who are not afraid to tell my failures, and my llimitations: who love in the truth and makes truth a lifesyle of love.
It is difficult to rub elbows with my neighbors, it creates friction, and sometimes it burns; but it opens the way to true communion. It is never good for man to be alone! Heaven is communion. Persons in hell are loners.
