Presence is another word for "Embodiment": being as fully present in the body as we can be. Bodies are miraculous machines as well as sometimes annoying encumbrances. We are a holy triumvirate: mind, body, & soul. Presence is really just about an equal relationship between the three.
In our culture, we often ignore spirit & just focus on the connection between mind & body: too often we treat the mind as the source of wisdom, and the body simply as the machine that carries out the mind's commands. But the body has it's own wisdom. The body is the keeper of our stories, the events that make up our lives. The body is also the container for our soul (we are not a body with a soul, but rather a soul inhabiting body).
It can be challenging to remain fully present in our bodies: especially if we inhabit marginalized bodies or if other types of trauma have damaged or severed our relationship with our body. And some of us have been indoctrinated with some form of the doctrine that states "the spirit is sacred while the flesh is profane" so subconsciously believe that our bodies somehow separate us from The Divine, and are inherently dirty.
In order to grow, passion needs an anchor. Our physical passions, our spiritual passions, our political passions, our creative passions must be anchored in the body.
