As with all things, your energy will ebb and flow. Flow with it. Do not push yourself when ebbing or overdo it when flowing. The very concept of flowing infers non-effort. Why all the trying when life is taking you along for the ride? Listen to the body. Watch the tides and mimic them. You are as much a part of nature as a tree. Bend and sway. That is the awakened way.
You are so very loved.
