I came across wonderful poetry by Daniel March written in 1869 and found it to be a religious text. That is not my reason for quoting the poetry, but because the description reminds me of the overwhelming joy it is, to walk in nature. When the clouds cast their shadows over hills and rivers, mountains and lakes in an ever-changing game.
The poetry of nature.

Clouds are among the most striking appearances in the natural world. Whether heralding the dawn with beacons of flame and banners of gold, or escorting the sun’s descending car with armies of light and sapphire thrones; whether clothing the mountains with garments of beauty, or enriching the landscape with flying shadows; whether shading the weary from the noonday heat, refreshing the field and the garden with gentle showers, or shaking the earth with mighty thunders; whether moving in silent and solitary grandeur along the blue deep of the sky, or covering the whole heavens with black and jagged masses, torn by the tempest and hurled onward like charging hosts in the shock of battle,—glorious in the morning, grateful at noonday, prophetic of the dawn at evening, clouds lend a charm to every landscape, a diversity to every season and a lesson to every thoughtful mind. No earthly scene could attract us long if deprived of light and shade from the changing clouds, and with our present feelings we should find it hard to be satisfied with heaven itself if it be one unvaried, cloudless noon. ~Daniel March, “The Balancings of the Clouds,” Our Father’s House, or the Unwritten Word, 1869
