As beliefs in ideas fade, go into the background or fall away, there is a more immediate experience of what is arising. Where thoughts would say I have seen this before, there is the immediate experience of whatever arises as always fresh, new, different.
In the same way, as beliefs fall away our words take on a fresh quality. They come out as fresh, new, and different, whether they appear to have been spoken before or not.
Freshness of experience
Thoughts arise with a question: is this similar to what has been experienced or said before? And then maybe, yes, it seems similar.
And if this thought is believed in, another set of thoughts may come up: yes, it is the same. I have seen or heard this before. Things should be new, yet this is the same old. How boring.
Thoughts can also be seen for what they are: as innocent questions, even when they appear as statements. They can provide useful and practical information in a conventional sense, as a help for orienting and functioning in the world. Yes, when they are not believed in, they remain as just guidelines of temporary and practical use only. And they too arise as always unique, fresh, different, along with anything else arising here now.
Freshness of expression
And the freshness of expression comes in two ways:
One is from the immediacy and freshness of experience, which gives the expression of it a sense of freshness as well.
The other is in seeing ideas as merely ideas, which gives a freedom in experimenting with how to express immediate realization and experience in different ways, relying less on what we have heard, read or said before.
The makeup of our human self probably plays a role here as well.
If it is happy with tradition and what is already laid down, it may use that as a framework for expression. There are many examples here of following collective or one's individual traditions.
If it has more of an adventurous and newness seeking tendency, it may explore new ways of expressing perennial insights, as Adyashanti and Byron Katie do. Or it may come up with something that combines these perennial insights with temporary insights and views in a fresh way, as Ken Wilber does in his aqal framework and Genpo Roshi with the Big Mind process.
And maybe most importantly, it may seek to grow, mature and develop so the ways the insights come out do the same. So there is a freshness in how it comes out, also in the context of its own history.
