Delicate, Tiny, Slight
You loiter on the mountain, reading off the digits of pi on this winter morning. The cold mountain air is so delicate, and changes only in very tiny ways — just like pi when you add another digit to it.
What other delicate things and tiny changes would you notice on the mountain? A little bird alighting in a tree, or the snowflakes it shakes loose from a branch? That's for you to decide, but imagine it vividly whatever it is.

Ah! Of course! The delicate bumble bee (び). Slightly out of place in winter, but this tiny creature is your idea of delicate. It lands on your finger, and you look at every tiny fiber of its being.
Picture yourself looking at the bee, thinking how each hair on its body is so delicate and tiny. Maybe it has a delicate aroma to go with it. A slight smell of honey?
