Summary of deleted text: In the winter, when the weather was cold and he needed big fire for heating, his contentment increased as he piled up the wood. As the season changed and the weather grew warmer, it was too warm for a fire.
The stacks of wood began to look different to me now. They stood at ready giving me confidence that here was enough. With the decreasing need, the desire to amass more diminished. I found that contentment did not consist of heaping up more fuel, but in taking away some of the fire.

Thank you for finding the context, MIchael3000. As you can see, the section that was given as a quotation did not contain enough context for other people to understand it.
What they have in mind is the idea that when it is cold, the bigger our woodpiles are, the more content and secure we feel. However, when the weather is warmer, a big fire will overheat the room, and we will be more comfortable with a smaller fire, or with no fire at all.
As I said, the fragment in the Forbes Book of Quotations does not work as a stand-alone quotation.
