Keep your faith in beautiful things;
in the sun when it is hidden,
in the Spring when it is gone.
Roy R. Gibson  

From December to March, there are for many of us three gardens:
the garden outdoors,
the garden of pots and bowls in the house,
and the garden of the mind's eye.
Katherine S. White

"The birds are gone, The ground is white,
The winds are wild, They chill and bite;  
The ground is thick with slush and sleet,  
And I barely feel my feet."
-  Winter Poems

Winter, a lingering season, is a time to gather golden moments, embark upon a sentimental journey, and enjoy every idle hour. 
John Boswell

Go to the winter woods: listen there, look, watch, and the dead months will give you a subtler secret than any you have yet found in the forest. 
Fiona Macleod, Where the Forest Murmurs
