Subsistence: the quality of having timeless or abstract existence. This song is a meditative chant based on the concept of ānāpānasati, meaning mindfulness of breathing.
Through mindful breathing we arrive back in the present moment and stop running. As a result we become more sovereign and free, bringing us back to the ultimate dimension, or reality.
You are one with all and all is one with you; there are no individual forces in the universe, merely different iterations of the same one.
