You are the awareness that’s witnessing the comings & goings of life. You have no qualities, no attributes other than you are aware – you’re not an object that can be described.
There’s nothing that can show up that can disturb you – for you just ARE. Notice that you’re observing even the thought or feeling of an ‘I’ that wants to identify what’s showing up and why it’s showing up. In this recognition you realize that anything can show up, nothing can be avoided or gotten rid of, life doesn’t need to ‘look’ a certain way, because you are simply aware. You are that awareness, you have always been awareness, you cannot NOT be awareness, for you are aware.
Notice that all that I say is not a prescription for something to do, rather is a description of how it is; you need no instruction or ‘practice’ to be aware.
And so you say “but it’s not always like this”, but it is… are you not always here, always aware? Do you-awareness need anything, does the feeling of peace, space, bliss or lack of thoughts need to be there in order for you to be aware? Are you not aware even when sadness or anger is here in the midst of an argument?
Awakening is the recognition of this awareness to be you. It’s a noticing – a confirmation if you like, that you are the awareness that witnesses all of life.
