Yes this would be one “provisional” method among many, maybe hundreds of techniques but they all seem to lead to the same place as one gets familiar. In Buddhist Vajrayana schools this is called “non-meditation”. The ultimate instruction is to simply do nothing, but this requires a bit of initiation (and paradoxically, concentration) to get right. Michael Taft has many different guided approaches to this on his chann…
Not familiar with the infinite gamut of techniques, and yes sounds right. It is possible, there are many ways, some people are curious about this state and lean into it, most are not. Who does, or doesn’t, and when, in my experience, is matter of grace. So no need to worry about it. I see it as something that happens to me rather than caused by willpower. Much like a memory or a flashback that then transports you.
The provisional techniques are great because different techniques click for different people. Once they've seen what it is, it's easier to drop in more directly. If there's any willpower involved, it's more a subtle dropping of discursive mental commentary (especially on the process itself: I've got it - almost there - why can't I get there today - ah so this is what works, etc).
Once you're there, it feels like the most familiar and comfortable place in the world. As one of my teachers said, this is real rest.
