Stillness Meditation is not about making the body and the mind still, it is about being the Stillness that we are. We are the still essence that perceives the movement of the mind, the body and the world.
Usually in meditation the aim is to still the body and mind, and that's fine. But we can never make the body and the mind truly still. Nothing in the world is truly still. It is the reflective nature of the world that makes movement appear. It is the reflection or opposite of True Stillness. This is the real nature of the world, just as the real nature of a movie is the screen. Stillness is the underlying and pervading nature of the moving world.
So in meditation we can 'sit back' into the unmoving, unchanging, formless, aware being that is not just the essence of our being. It is the essence and the whole of all apparently separate beings. It is at the heart of each being, yet it is That in which the beings seem to appear.
This Stillness Meditation is the untangling of identity with movement and change. We withdraw from the fascination of the world and the distractions of the body and the mind. It helps for the mind to know that its identity is not this body. It helps for the mind to know that any limited defined identity is flawed, and that our true nature is without limits. Indeed, our true nature is aware of the apparent movement and activity of the mind.
We need to bring the mind deeper to rest in the witnessing of the mind and the body. Effectively the mind untangles itself from its false identification, as we remain the Unchanging One perceiving change.
In practice we allow the body to sit comfortably. Before closing the eyes, we recognise that we are perceiving this. We close the eyes. There are still sounds, but we recognise that we perceive them right here. We allow the mind to ease off a little. Thoughts will likely still appear, but we withdraw further from the thoughts to the perceiving of them. This may involve some to-ing and fro-ing, as we withdraw then become caught up in the thinking again. But none of that thinking is important right now, so we let it go again and observe.
With practice we go deeper. That's when the untangling of identification takes place. It is the mind that is going deeper to the source or essence. The nature of the mind is not separate from the source or essence, of course. It is the source or essence. This Stillness Meditation seems to bring the mind inwards to the source of Awareness, where there is really no inside or outside. There is only what seemed to be the source.
Know that you don't really have an inside and an outside. You are not the movements of the mind and the body. Yet all movement appears within the Infinite Stillness that we are. There is none other than this Infinite Stillness. It is the Infinite One Aware Being. That by which all is perceived. If you can perceive it, it's not you. If it is seen to move and change, it's not you. You are the Unchanging Awareness that perceives movement and change. This Stillness Meditation is no meditation. It is just being as you are. Pure Clarity.
