“Each cloud-capt mountain is a holy altar;
An organ breathes in every grove;
And the full heart 's a Psalter,
Rich in deep hymn of gratitude and love.”

The Iliad of Homer: translated into English blank verse (1791), Book VIII, line 643.

Context: Only those who are spiritually imitators, only people who are afraid to be grateful and too weak to be loyal, have nothing but the present moment. The mark of nobility is inherited possession. To a noble person it is a holy joy to remember, an overwhelming thrill to be grateful, while to a person whose character is neither rich nor strong, gratitude is a most painful sensation. The secret of wisdom is never to get lost in a momentary mood or passion, never to forget a friendship over a momentary grievance, never to lose sight of the lasting values over a transitory episode.

Context: p>We have come by curious ways
To the Light that holds the days;
We have sought in haunts of fear
For that all-enfolding sphere:
And lo! it was not far, but near.We have found, O foolish-fond,
The shore that has no shore beyond.Deep in every heart it lies
With its untranscended skies;
For what heaven should bend above
Hearts that own the heaven of love?</p

Cold Mountain Transcendental Poetry

Though she is quoted as saying this in a 1996 interview, she is quoted as saying it is a maxim which she follows as a Christian Scientist, and it seems to come from words of a Christian Science Hymn. It does come from Hymn 249 in the Christian Science Hymnal
