When you feel as though you haven't moved be it mentally, emotionally, spiritually, or physically it is frustrating.
We, or many of us, feel we should be growing , changing, doing, evolving, if you will. When we don't it can seem like stagnation, failure.
We're taking a break. Constant inner change requires rest periods same as physical exercise. No one spends every minute of every waking hour in sustained physical activity and neither should we spend all our time stretching our minds or souls or emotions.
Stretching causes breaks. To stave those off we must take breaks.
That said, if the break goes on too long for your individual taste, then yes, it may be stagnation. No one wants that.
Get moving, reading, meditating, praying, or learning one new thing.
But how do you tell?
By listening to yourself and no one else.
Our friends and family know exactly what is wrong with us and how to fix it, They have all the answers. Just ask them, they'll tell you.
But as long as you are looking outside you will ignore looking inside and inside is the only place where your real answer is found.
So take the break. Enjoy it. Plenty is going on when you feel like there's nothing happening. All you've learned, done, experienced, felt, or heard is being assimilated. Just like the individual flavours in a recipe need time to rest and gather, so do you and your experiences.
Let it happen.
Forcing it will only increase your frustration.
Relax, and listen to yourself.
