There is no light at the end of the tunnel. You are the light and the tunnel. You are looking for something to change, for something to be different. In that you assume that this, right here and now, is not it. You assume that what IS, right now, is not good enough, that something else needs to arrive in the form of some state or experience.
The only concern is the idea you have about yourself, about what you are, about reality. Look and you'll notice that everything you believe, therefore everything you think you know, is based on the idea of separation, of independent existences. You have mistaken the coming and going of forms or appearances for the coming and going, the creation and destruction of existence.
It is not existence which comes and goes. What appears is not an absolute "thing". It is not a stand-alone existence. It was not popped into existence from nothing - not existing, then existing, then ceasing to exist.
The ocean is there - then the ocean expresses as a wave. The wave is an appearance OF ocean, a form OF ocean, something ocean is doing. Wave did not come into existence. There is no such "thing" or entity as "WAVE" apart from ocean. If we speak of wave doing this or that, we are speaking conceptually, because it's really OCEAN doing it. It's ocean-appearing-as-wave. We don't need to speak that way because it's clumsy however we have somehow been tricked by the convention of naming appearances, naming activities or expressions.
Tree is Life "treeing". Life-appearing-as-Tree. Yes?
Rock is Life "rocking".
There is no "thing", no stand-alone existence called "tree" or "rock". There is only Life or Existence appearing or expressing AS what we call TREE or ROCK.
All "things" are like this. The body and thoughts are expressions of Life. The body took shape but did not come INTO existence. Existence took shape as BODY. Yes? Life took shape as what we call "body".
And then body will cease to function, naturally. It will take it's last breath, beat it's last heartbeat, and then it will stop functioning. Consciousness will cease to return. That window or perspective or kaleidoscope will close. But nothing happens to Life. Nothing happens to Existence. The wave crashed to the shore and dissolved back into ocean. Nothing happened. Ocean remained ocean. Life remains Life.
The question is - who is present right now, aware or expressing as this appearance we call Consciousness, this stage upon which the stories play out? Who is the intelligence which can say "I EXIST"? Who is seemingly looking out the eyes?
Isn't it Life? Isn't it that Existence or Intelligence? Aren't you Life itself, aware of itself, so to speak? Aren't you that Intelligence, that singular existence?
"Reality is whole and you are that."
"The world is Brahman - ultimately "I" and Brahman are identical."
"You are already what you are seeking."
It isn't difficult. The difficulty lies in breaking with the idea that reality is made up of independent "things" or "EXISTENCE-S", that you are just one of these existences and your existence is finite and separate.
It is not.
