Yogi: There was low energy and it doesn’t take much to bring it to balance. 

Sayadaw: Low energy is an easy state to work out of. You just have to recognize it continuously and the energy becomes stronger.

For someone who already understands, they don’t panic because they know what to do and they work at it steadily and the energy will build up.

If defilement is not mixed up in the perception of the experience, then whatever you have to do is easy.

Even if there are a lot of defilements and the mind is off balanced, so what? 

Just be mindful continuously and the mind will become balanced.

It is only a problem when we reject the experience. 

A mature yogi doesn’t force or reject anything. They accept it and that’s why it is easier to regain balance.
