Presence is completeness. When you finally understand what Presence is, when you’re completely present, you are complete. There is the valuing of Presence: there is the perception of completeness. When you’re complete you’re content with being present. There’s no need for anything else.                                           A. H. Almaas (Diamond Heart Book 3, pg 99)

Presence is more like feeling than like thought, which makes it possible to mistake it for the felt aliveness of the body. The unconscious components of the self-representation (like those involved in the primitive body sense), coupled with the assumption that the physical body is the most fundamental level of the self, tend to prevent one from discriminating Presence in experience.                                                                           A. H. Almaas (The Point of Existence, pg 77)

The “Presence” being spoken of on this page also requires the stillness of mind referred to in this quote:

Stillness means ‘being free from thoughts’ and yet aware.             Sri Ramana Maharshi
