Once, I felt the tingles you describe while mentally scanning my body before sleep, stopping at a particular lower-spine point and all. Making the connection between that experience and subtle body stuff is what broke me into thinking that /x/ stuff wasn't all larps. 
I'm considering attempting this, but more context would be nice. What happens if I do this without
>depleting energy & resources that are available to the concious mind
and what place does this practice have in a broader framework?

Consider how the mind functions after being awake for 24 hours.
Mental lethargy.
Those three remove the energy from the conscious mind need for evaluations, decisions, judgments etc..
They prevent the conscious mind from becoming a roadblock to the process.
They are also present in many ancient and modern rituals.

I get that. There have definitely been times when my standard mode of thought kicks in and takes me out of a non-standard state, but that feels as much like a safeguard as a barrier.
