To be fully human is to be fully a speck.
In our essence, we’re limitless, sky-sized, changeless and forever. The body, obviously, is time bound. Since the illimitable cannot be limited, we are in our essence not bodies. We’re spiritual beings temporarily enfleshed.
What we do may bring happiness to others but work will not bring happiness to ourselves. If we were human doings, yes, that would be the case, but we are beings, not doings.
There are periods when we feel connected and alive, and there are other periods when we feel alienated and spent. Nothing wrong with that. We are spiritual beings having a human experience.
