I understand, but I'm not so sure everyone else does. It's as if for some people, there's an assumption that visualization is all that's required, and if one just does it enough, the thing that is visualized will somehow manifest into one's life.
More responsible interpretations tend to emphasize that success requires a combination of visualization and action ( work ). After all, even winning a lottery requires one to go out and buy a ticket.
As the old poet said: “The Truth was a mirror in the hands of God. It fell, and broke into pieces. Everybody took a piece of it, and they looked at it and thought they had the Truth.” ~ Rumi
Fact is, your comment about manifestation needing action/work suggests to me that you're getting an aspect of it (not all) - when is the moment for action? What action? How do you know? What aspect of the human psyche must be alight (engaged) to know what that 'action' is to begin with? If one starts to play with manifestation one starts to suss out how it works, and 'recognizes' truth when it is spoken by a fellow traveler/experimenter. You might be surprised at what a 'late stage' action/work enters the picture, and how subtle and pervasive it is.
Here is a young enthusiast presenting his ah-ha revelation. What he presents is very familiar to anyone who has done magic working (witchy stuff ). In that (cultural) context one would use designated cups, likely special in some way, 'dedicated', blessed, wrought in symbols to evoke the divinities to create a sacred space, etc. There might be a sound - an incantation. But here it all is very simply....
This Manifestation Technique Can Change Your Life (The Two Cup Technique)
Mainstream science is speaking about sound and the impact of the presence of the electrical/vibrational being of the living human on what is around us, down to the atomic level. So it is that much of this stuff that was buried in the mysticism of the adepts starts to have resonance for the modern mind - there is a logical entre. There is a reason why the placebo effect in medicine (these days) is recognized in medicine as a valid healing attitude: the mind does impact the body, what we believe does effect change. 'Christian Scientists' (religion) have long worked with this, though they hit walls when the physical is 'dense' enough that the velocity of 'mere thought' in one lifetime cannot make headway through the knot. One has to consider what is possible in the short term, and what requires an eye to the long game. For those who have experienced manifestation they recognize it's 'laws' as we recognize the constraints of gravity.
Did not. A 'treasure trove' of what?
