Your body is an anchor for presence.
Presence not only has to do with becoming aware of perception and the activity of the mind, but becoming aware of the energy within the physical body as well. Although our essence is the formless aspect of our being, we are also connected to and inhabit our temporary physical forms that exists here within this collective reality.
To learn more about this connection between the form and the formless, one can look into concepts such as Chakras, Kundalini, and Tantra. (These are just a few examples that have helped me, but there are many more).
It is important to treat our bodies as our temples, and remember to not neglect this aspect of ourselves.
