Having spent a long time over the years paying close attention to my thoughts during many hours of mindfulness practice, I have noticed that it is possible to be aware of thoughts on a level before they are expressed as word-like thoughts, that is before they manifest as an inner dialogue of sentences. Awareness of the process of thought has led to a realisation that thoughts first arise as whole concepts, as complete ideas, knowable instanteouly. It is only later that the linear string of thoughts emerging over time is experienced in the mind. When this awareness of whole concept thinking has been established it is then possible to keep the thoughts at this stage and not continue to the inner dialogues. This gives the mind a lot more space and time, freeing it of the clutter of an inner dialogue; concepts arise and are instantly knowable without any time needed to express these whole ideas in a paragraph of internalised sentences.
