I don't have a strong belief that this experience won't generalize, but, I want to flag the jump between "this worked for me" and an implied "this'll work for everyone/most-people." (I expect most people would benefit from hearing this suggestion, just generally have a yellow-flag about some of the phrasings you have here)
I think it's both true what you say, that removing blocks can give you instant improvements that no amount of practice ever would, and also that one can make progress with practice in the right conditions.
One way I parse this is "the skill of being present (may be) about untangling emotional blocks that prevent you from being present, more than some active action you take."
It's not like entangling emotional blocks isn't tricky!
Some meditation advice has a vibe like... “To become more present, all you need to do is practice! It's just a skill, like learning to ride a bike 😊”
This never worked for me. When I tried to force presence through practice, I made little progress.
Being present isn't a skill to build — it's the natural state! What blocks presence is unconscious predictions of bad outcomes. Remove these blocks to make presence automatic.
Now, you might wonder: if presence isn't a skill, why do some people seem to benefit from meditation practice? In my experience, meditation can help with noticing blocks and creating space to work with them. But the practice itself isn't building presence so much as creating opportunities to identify and release blocks that prevent presence. This is what I believe explains why some people can meditate for years without becoming much more present, and others grow quickly once they find and integrate their core blocks.
Most of what I’ve done to develop more presence is ask my system: “What bad thing happens if I'm fully present right now?”
One last thing: Once you become fully present, you may be tempted to think “Oh, I get it now! Being present is so simple! Just be present!” But that will overlook all the little blocks you untangled along the way. (Once blocks are untangled, they are forgotten!)
Natural presence is already there, waiting to be uncovered. Find the blocks.
See how I put this into practice.
