I just sort of go… hard to explain, but I’ve been doing it since I was little and then for a while I formalised it using methods taken from core shamanism, where I was using a “world tree” and stuff, but a spirit I trust told me that was limiting and I’ve gone back to “just do it” mode because of that guidance.
This is the method taught at core shamanic trainings: http://www.corpshaman.com/before.asp - ignore the stuff about the power animal because it looks like you have that sorted. 
I’m rebalancing after some big energy shifts in the past few days and feel totally weird right now, I just spent most of this afternoon asleep and still feel zoned-out, but would definitely be up for a meeting in the astral later on.
