Do not affirm or defend your form identity.
-Eckhart Tolle

Tolle echoes what A Course says about the body living in this world of form.  Identifying with form is nonsense because form is impermanent.  Yet we do so much, don't we, to affirm who we are based on the ideologies of the physical world?  We identify with our bodies, with what we own, where we live, what we do. and we will go so far as to defend or even attack (sometimes kill) to preserve this identity, won't we?

The Dali Llama, as well as all Buddhist sages, teaches "Nothing is permanent." We will lose the things we worked so hard to gain, we will lose our possessions, our things, our social recognition,...and we will lose our youth, our health and our physical bodies eventually.  Identifying with this world will only bring pain and suffering (Dukkha)

Nothing of this physical world will last so why do we identify with it?  We fail to realize that we are so much more than this body.  Eckhart Tolle reminds us,

"At the heart of you, and at the heart of the universe, which is the same thing there is a timeless essence.  Yes there is a temporal you[a physical you; a body] ...and there is a nonphysical being, a higher self and then there is the transcendent dimension."

Why limit ourselves to the temporal when are so much more? Why suffer when we can embrace our beingness?  Why stay stuck in this limited and painful dimension when we can transcend it by being fully present and alive?  We can be transparent allowing this timeless presence to shine through or we can be fearful, hiding it behind imagined borders that need defending.

The thing is this presence we hide away in separate  body forms is not separate...It does not belong to me...and it does not belong to you.  It is something that can not be owned or possessed nor can it be separated by body lines. It is everything and everyone.  You are this presence; I am this presence.  How then  can it be attained, contained  and subject to loss?

Bodies do not need protection from other bodies.  These lines can not hold back who we really are.  Though it appears we are separated by flesh, we are not separated by presence.  Presence is Love. Exchange fear for Love and see this higher Self shine through. 

Love your neighbour as yourself because you know your neighbor is yourself.-Tolle

All is well.
