Simple is not easy

Spiritual teachers say it is simple.  Just be aware.  Be in a moment. 
Aikido sensei says it is simple.  Technique is from simple and natural movements of the body.
But, simple doesn't mean easy.  We have been trained how we make and see things complicated since we were kids.  Everything is not supposed to be that simple. 
The nature is simple, then we don't know how we can be simple like the nature. 
We need to take off a lot of coats that we have kept layering for years.  Some coats are so heavy that we can't easily take them off.
Just like an onion, when we keep peeling the skin, we reach the core and then nothing.
Peeling onion skins makes us cry!
