We can smell things all the time, but we don’t think about what we smell unless it really stands out. If it is something that is pungent or extremely pleasant we think about it. Otherwise, it just blends into the background.
This is true of all our five senses. It is even truer of perceiving energy. It has become so second nature that it doesn’t even register for most of us. This is the issue. It is only those who strip off the other senses through meditation/ prayer that experience it, or those who submerge themselves in nature that revel in it.
It is the same concept of first going into the water and being struck by the temperature, but then getting used to it and feeling at one with it. Energy is the pool water of life.
