“(…) Salvation is to see things as they are. (…)”

A Christian Manifesto (1982)
Context: His death there on Calvary's cross is for us individually, but it's not egotistically individualistic. Our individual salvation will one day be a portion of the restoration of all things. It is our calling until He comes back again that happy day, to do all we can — while it won't be perfect as when He comes back — to see substantial healing in every area that He will then perfectly heal, and that Wesley did understand.

1950s, New Hopes for a Changing World (1951)
Context: Man, in the long ages since he descended from the trees, has passed arduously and perilously through a vast dusty desert, surrounded by the whitening bones of those who have perished by the way, maddened by hunger and thirst, by fear of wild beasts, by dread of enemies, not only living enemies, but spectres of dead rivals projected on to the dangerous world by the intensity of his own fears. At last he has emerged from the desert into a smiling land, but in the long night he has forgotten how to smile. We cannot believe in the brightness of the morning. We think it trivial and deceptive; we cling to old myths that allow us to go on living with fear and hate – above all, hate of ourselves, miserable sinners. This is folly. Man now needs for his salvation only one thing: to open his heart to joy, and leave fear to gibber through the glimmering darkness of a forgotten past. He must lift up his eyes and say: "No, I am not a miserable sinner; I am a being who, by a long and arduous road, has discovered how to make intelligence master natural obstacles, how to live in freedom and joy, at peace with myself and therefore with all mankind." This will happen if men choose joy rather than sorrow. If not, eternal death will bury man in deserved oblivion.

An Integral Spirituality
Context: Attunement could occur through any of the great religions, but would be tied exclusively to none of them. A person could be attuned to an "integral spirituality" while still be a practicing Christian, Buddhist, New-Age advocate, or Neopagan. This would be something added to one's religion, not subtracted from it. The only thing it would subtract (and there's no way around this) is the belief that one's own path is the only true path to salvation.

The Seduction of the Minotaur (1961); the documentation of the conflicting citations available on this page ( HNet http://h-net.msu.edu/cgi-bin/logbrowse.pl?trx=vx&list=H-Judaic&month=1108&msg=RizwZWCgeA8woVU9mNOEYQ) seems very thorough, and in the end attributes the quote to this novel, which includes the line:
Lillian was reminded of the talmudic words: "We do not see things as they are, we see them as we are."
With Nin's description of the statement as "Talmudic" it afterwards began to be attributed to the Jewish Talmud, without any cited version or passage.
Similar statements appear in You Can Negotiate Anything (1982) by Herb Cohen: "You and I do not see things as they are. We see things as we are"; and in Awareness (1992) by Anthony de Mello: "We see people and things not as they are, but as we are".
Another similar statement without cited source is also attributed to Nin https://web.archive.org/web/20050322041559/http://learn-gs.org/learningctr/tutorial/4.html: We see the world as "we" are, not as "it" is; because it is the "I" behind the "eye" that does the seeing.
Disputed
Variant: We don't see people as they are. We see people as we are.
