Is energy only needed to set things in motion?

I do a bit of dancing in the morning as part of my morning workout. In this dancing I’ve discovered sort of a flow state, where I intend to do certain moves and then just relax into the rhythm, using my whole body and as little muscular tension as possible. This has the effect of me more or less letting go of my body, and I can be very present in the moment and reach what I would describe as an altered state. I don’t do anything that my body isn’t normally capable of, but I definitely transcend my mental limitations that normally restrain my body. 

What I noticed the other day, is that when I set the intention of doing a certain move, I have to use a little bit of force to change direction. How much or little force I have to use, depends on how fast I can get back into the flow. Sometimes I lose myself in thoughts, which is something that more easily happens when a change in direction occurs. When this happens, I soon find that I’ve exhausted myself. And if I observe what my body is doing, I discover that unnecessary strain and tension has crept into the moves as well. 

I then tried this with the rather simple tasks at my work, when I remembered doing so. And the results were similar to those that I experienced dancing. 

I don’t know if this was related, but when I lost the flow and presence, more I got more clumsy and careless than usual. I tipped things over and was not thinking at all about what I was doing. It was almost as if life wanted to show me that I was no longer in this higher state.

It feels as if using as little energy as possible is key here. And that this can be applied to all areas of life. Right now, I can’t see how this could be applied to more complex tasks. But somehow I believe that it could. Maybe I actually get into contact with something higher (dare I say God?) when in this state? And maybe there is no end to what this higher (God?) can do through us, if we just let go and allow?
