There is no bad without good.
There is no high without low.
There is no forward without backward.
I am not sure if there is a math pattern in this as in high-low-high-low or high-high-low-high-high.
But I am sure that everything will pass, the bad day will be gone so will the good day. The serene high-energy field might be replaced by a low-energy field. Two steps forward might be replaced by a step backward.
So what can we do?
Dance with it!
Learn from it!
Surrender to any situation and keep moving forward.
