Look into the awakened mind of your own awareness! It has neither form nor colour, neither centre nor edge. At first, it has no origin but is empty. Next, it has no dwelling place but is empty. In the end, it has no destination but is empty. This emptiness is not made of anything and is clear and cognisant. When you see this and recognise it, you know your natural face. You understand the nature of things. You have then seen the nature of mind, resolved the basic state of reality and cut through doubts about topics of knowledge.

This awakened mind of awareness is not made out of any material substance; it is self-existing and inherent in yourself. This is the nature of things that is easy to realise because it is not to be sought for elsewhere. This is the nature of mind that does not consist of a concrete perceiver and something perceived to fixate on. It defies the limitations of permanence and annihilation. In it there is nothing to awaken; the awakened state of enlightenment is your own awareness that is naturally awake. In it there is nothing that goes to the hells; awareness is naturally pure. In it there is no practice to carry out; its nature is naturally cognisant. This great view of the natural state is present in yourself: resolve that it is not to be sought for elsewhere.

-- Padmasambhava, Guru Rinpoche
