The state of mind "there is no state of mind which is better or worse than the other" is the best state of mind because it is above all states of mind. Holding on to it, one is free to experience life fully without resistance or objection.

"This too shall pass".

The good eventually turns into bad, and the bad eventually turns into good, but above the passing clouds the sun always shines.

That is the non-dual perspective.

It is in a sense, higher.
