A common mistake about Non-Duality is that it is something to be attained, or it is a state of consciousness that we can reach beyond this world of duality. But Non-Duality is really an explanation of the nature of reality - that it's not two, meaning that there is not a duality or a multiplicity, there are not many. Sometimes people may feel that it is necessary to overcome duality by drawing inwards to a point of Non-Duality, but that's not the case. It is rather a recognising that there is no duality, no inside or outside, that reveals the true nature of reality as a Non-Duality. Let's understand this some more.
Most people may have no concept, understanding or interest about whether reality is a oneness or not. There is a generally accepted view amongst humanity that there is this and that, me and you, me and them, these and those. It is what we call a dualistic view, seeing the world as consisting of many separate forms. People generally don't realise it in that way; it's just how the world appears and their everyday view of life isn't really questioned or highlighted. The Non-Duality understanding points it out. It highlights that we see the world in this way, mentally - that we have a mental view of the world as made of separate forms and separate beings. I describe it as a World of Opposites, because not only does the world appear to be made of separate forms, but there appears to be a force of opposites through the world, where these opposites seem to be stretched apart. For example, we conceptualise high and low, good and bad, near and far, stillness and movement, permanence and change, and so on.
So it's useful to recognise this apparent World of Opposites, and that the world behaves as if there is a push and pull between opposing forces. Moreover, it's useful to recognise that we see the world that way and we believe that this separation of opposites, or the separation of the world as a multiplicity, is true and real. That's an important recognition. But Non-Duality goes further. It says that this apparent separation and appearance of the interplay of opposites in the world is not really how it is. There's not really a separation. There are not two. There are not many. Only an Infinite One.
Just as a painting appears to contain many forms but is one, just as a movie on a screen appears to have many forms but is one, the appearance of the world in consciousness is one. The play of an unfolding universe is one. Although it may seem that the universe came from an unmanifest Singularity, bursting forth into opposite forces that interacted and multiplied, really the Singularity remains. There is no creation and destruction. What appears or disappears from the Singularity is always the Singularity, although it may appear to be its opposite. The universe now is no more or less than ever.
So Non-Duality is not something to be reached. It's right here now. It's not something for which we need to raise our consciousness to attain. Rather, it is recognised in the letting go of the ingrained human belief of separation. It's not that we live in duality and need to reach a state of Non-Duality. There is no duality. There is only Non-Duality; there is only an Infinite Indivisible Oneness. The world is not a duality. It appears to be, but what appears is a play of opposites within the Oneness of Reality. The world cannot appear without a play of reflection: what is and what is not. But it is all What Is.
It's hoped that humanity can take this on board and start living in a way that recognises the Oneness of life. Non-Duality does away with selfishness, competition, fighting and war. There are no separate selves. There is only Infinite Oneness.
