my vote: Normal and natural
This symbol (a sine wave) represents how most things in nature move through changes.
up-down-up-down.
inhale-exhale-inhale-exhale
expand-contract-expand-contract
but as you move through a growth and strengthening process, there’s a gradual upward trend to the waves.
Just treat it as natural. When you’re up, ride the wave. When you’re down, smile with peace and rest.
Every part of the cycle has its purpose.
The down times are a great time for cleaning-up, resting, etc. (Think of an office building at night time. When the offices are empty and various staff come to clean-up or tune-up the computers, etc.)
Down times are also good times for planning your next moves for when the next inflow of energy comes.
Don’t waste your fall and winter times mourning for the summer that just ended. Instead, plan and prepare to harness and enjoy the next spring and summer.
