My neighbors have a greenhouse attached to their kitchen, and it is looking spectacularly summer-ish right now. Impatiens, begonias, and verbena are still blooming. Add 2 dashes of mums--pink and yellow-- and i smile every time i look into the greenhouse.
Just outside the glass walls and glass roof, the temperatures are below freezing. The greenhouse is cool, yes, and the flowers love it.
One description of the meditative absorptions (jhanas) is that it's like sitting under a glass jar: Outer sounds are muted, and body sensations drift away to a distance, so the sense of the body becomes rather amorphous.
"Inside" the meditative absorptions feels happy and calm despite whatever may be going on outside.
The greenhouse is a protected space. So is meditation.
