Spring passes and one remembers one's innocence

Summer passes and one remembers one's exuberance

Autumn passes and one remembers one's reverence

Winter passes and one remembers one's perseverance.

- Yoko Ono, Season of Glass

2.Winter is an etching, spring a watercolor, summer an oil painting

and autumn a mosaic of them all.

- Stanley Horowitz

3.Poetry of John Keats (1795-1821)

The Human Seasons

Four Seasons fill the measure of the year;

There are four seasons in the mind of man:

He has his lusty Spring, when fancy clear

Takes in all beauty with an easy span:

He has his Summer, when luxuriously

Spring's honied cud of youthful thought he loves

To ruminate, and by such dreaming high

Is nearest unto heaven: quiet coves

His soul has in its Autumn, when his wings

He furleth close; contented so to look

On mists in idleness--to let fair things

Pass by unheeded as a threshold brook.

He has his Winter too of pale misfeature,
