For us there is only one season, the season of sorrow. The very sun and moon seem taken from us. Outside, the day may be blue and gold, but the light that creeps down through the thickly-muffled glass of the small iron-barred window beneath which one sits is grey and niggard. It is always twilight in one's cell, as it is always twilight in one's heart. And in the sphere of thought, no less than in the sphere of time, motion is no more.
Is it thy will that I should wax and wane,
Barter my cloth of gold for hodden grey,
And at thy pleasure weave that web of pain
Whose brightest threads are each a wasted day?
Just as a stream flows smoothly on as long as it encounters no obstruction, so the nature of man and animal is such that we never really notice or become conscious of what is agreeable to our will; if we are to notice something, our will has to have been thwarted, has to have experienced a shock of some kind.
