...there is often suffering. Although like the old Buddhist quote "There is suffering but no one who suffers".
What is it?
Not sure what you're asking.
Telling yourself that it is like that when it's not clear is just feeding a belief. And this is the very hindrance of it becoming actuality.
There might be a profound knowing that it is true. But as long as it is not clear, please refrain from utilising it as an appeasing belief!
Occasionally there is a "knowing that it is true", but its occasional and not usually "profound". In terms of not using statements like the one I quoted above as "appeasing beliefs", I just want to be sure what you mean. For example, there's an LU app on my phone that I occasionally look at. It has various statements about there being no self which I find helpful to glance at every once in a while. I guess you're saying that reading things like that shouldn't be a substitute for LOOKING...
Without thinking about it, but by LOOKING at it:
What is the difference between a "deliberate thought" and another thought? What can be observed?
When I try to think of something deliberately (for example, I just tried to visualize a red guitar), there is a sense of tension and focus accompanying the image. Other thoughts just arise without any tension/focus.
Is there an actual difference, or is it just the content that's different?
There's no difference in the content of the thoughts - just images or words appearing.
What tells there is a difference?
When I try to think a deliberate thought, it feels like there is an "I" trying to produce the thought. I've looked at this carefully in the past though and realized that just because there is an experience of tensing and focusing, it doesn't mean there's anyone doing this.
