Thanks Starbuck! This really focuses the discussion well and has great potential to lead to something fruitful in the manner Ashvin intended in this thread.Starbuck wrote: ↑Sun May 30, 2021 9:31 am "Being a limitation or fragmentation of reality or truth, the process of thinking is always tending to return to its source or origin, and it is because of this that the disciplines of philosophy and science exist in our culture. Every thought process or the line of reasoning that a philosopher or scientist embarks upon is a process whereby the finite mind is tending to return to its source. That is why all philosophers and scientists desire one thing alone which is understanding. Their thoughts tend towards understanding. The experience of understanding is the dissolution of the process of thinking, into its source of consciousness. It is for this reason, contrary to popular belief, that for some people ‘thinking’ is a spiritual path. It is as legitimate spiritual path as any other path."

Let's look at the above more closely. What is called the source or origin of thinking? In order not to be lost in abstractions let's try to follow the actual experiences and simply describe them.
Let's follow this thought dissolution process. We begin our meditation from the ordinary state. In the beginning we are in quite beta brainwave state, experiencing hectic reverberations of whatever we've been doing so far. As we relax our inner activity we gradually move more towards a more floaty state where we're still drawn by inner rhythms but in a little more relaxed way. For example, we reexperience some events of the day, we return to feelings that someone aroused in us with what they said, we continue to argue with someone in the forum

So far so good. We are fully objective in the description of our meditative experience. We simply report the contents, we're not speculating what comes from where, what lies behind what and so on. Let's move on to the origin of thinking. When the thinking process has been dissolved there are many things that could be experienced depending on different factors. If we go gradually, once the thinking process is dissolved we find ourselves into something which we can describe as a laminar soul flow. Eugene calls it coming and going of phenomena. The characteristic thing is that there are no discrete thought-forms - words, symbols. If we go even further we can reach the void state but at this moment there's no need to go that far. Note that the above progression is described from a perspective of popular meditative approach. If we had spiritual-scientific training there are differences once the intellectual thought-process ceases but hopefully we'll address these in other posts.
So we've managed to dissolve the thought process and observe the laminar flow. From this position we can go back and forth and experience the emergence and dissolution of the thought process and thus investigate it. OK. So what do we call the source or origin of thinking? In most popular nondual terms we would receive the answer that the laminar soul flow (synonymous of consciousness) is the source of thinking. Here we must already be very alert. By saying something like this we already add certain ideas to the given through our thinking. Let there be no illusion about this. The experience of the laminar soul flow is what it is, it's a given experience we can attain to. But when we say that this flow is the origin of thinking we already add something extra to the given which colors it. We should really observe this very well because it is precisely this sort of things that falls completely in our blind spot. What is the fact of observation? That at one point we experience the unbroken soul flow and then rigid and isolated thought-forms begin to form. This is the certain thing. But when we say that the soul flow is the origin of thoughts, we assert something which is not a direct result of observation. This is a simple thinking error. It would be the same as to say that the ripples on the surface of the sea originate entirely from the water, that the water is the source of the the ripples. But we know that this is not the whole picture. There are fluid dynamics in the water volume but the picture becomes complete only when we account for the wind interacting with the water surface.
So what Spira describes amounts to: "science and philosophy's ultimate goal is the realization that the thought-forms that constitute them exist as ripples on the laminar soul flow and the flow is the reality". Let us be clear. What the dissolution of thoughts really tells us is that there's a more general medium of our soul in which the ripples of the thought-forms emerge. This medium is most often simply called consciousness. So we have "consciousness is the source/origin of thoughts". But what does this really tell us? Not much actually. It's just as useful as the materialist's "the brain is the origin of the thoughts". The latter imagines the thoughts as pixels commanded by inaccessible (to direct experience) hardware. The former attains to the experience not only of the pixels but to the screen (which is found to exist even if all the pixels go off) and it's decided that the screen (which is called consciousness) is the source of thoughts.
What both of the above positions miss is that we have another factor which is simply not recognized in most cases - it falls into the blind spot. It's the fact that there's something else which we can call the source of thoughts and it is our spiritual activity. It is the wind above the soul water surface. It's not a coincidence that the ancients spoke of breath, which is related to the air element and is generally synonymous to spirit. When we say "consciousness is the source of thinking" we really project the source of thinking to something belonging to the phenomenal world (world of perceptions). And no doubt this is an experiential fact for many people. They are really thinking machines, they hear in their heads torrents of words but they say that either the brain thinks or consciousness thinks. They put the source of thinking outside of themselves. To experience the source of thinking within ourselves we must want to do it. Nothing external can force us to. If we experience meditatively a thought like "I think the words" we can experience something which is nowhere else to be found - a causative idea. This should be grasped well. The popular slogan is 'there's no thinker, there's only false identification with thoughts'. But this simply uses thinking to pass ignoring judgment to something which we can't derive from anywhere else.
Let us end with this. We should meditate on this distinction. On one hand we have the popular idea that thoughts simply bubble up as if from the cosmic microwave background radiation. In other words we place the cause of thoughts to something mysterious and unknown. We reduce our spiritual position to that of a passive observer which has right conception of itself when it avoids to identify with thoughts and instead says 'the thoughts think themselves'. On the other hand we have an observation, something of the given, which can be justifiably called a cause. Actually it is the only cause of something within the World Content that we know from direct experience. When we experience our thinking (and not only the thoughts) we have the clear experience of causative spiritual activity, it's the wind that creates ripples within the soul flow. We should really be clear that there's no point to call this spiritual activity an 'illusion' or 'false identification with thoughts'. It could be described as illusion if we could show the reality from which this illusion emerges but we can't do that. There's no such causative activity within the soul flow itself. So we make quite an arbitrary assertion if we say that the causative spiritual activity is a mere illusion emerging from the soul flow. It's just as hard problem as 'consciousness is illusion created by neurons'.
So I hope that with the above we have a more concrete pointer to what we consider to be thinking in the deeper sense. It's not an abstract speculation, it's a living experience that anyone can have, if they have the good will to do so. We only need to allow ourselves to experience how our spirit-breath creates the thought ripples. If this is understood we should really say "I, the spiritual being which utters these very words, am the actual source of them. I think the word-forms. Any attempt to explain the thoughts as originating from something other than me, simply alienates me from the very thing that I produce. I simply refuse to take responsibility for my own creations."
Let's see now who will allow themselves to experience their thinking spiritual being and who will use the freedom of their spiritual being only to produce the thought which denies responsibility for all other thoughts - "I don't think. The thoughts think themselves".
