i guess one option would be to detect physicological markers that indicate the transition is happening and then induce an active brain state…some people have suggested binaural beat generation can induce particular brain states by playing in a particular frequency (8-12 Hz)..like theta for active recall.

We sell “receiver” units to regular consumers that connect to the internet and receive this Buddhist monk’s brain transmission. The consumers wear the receiver units on their heads. And the device tells them how far off they are from having the same brain patterns as the Buddhist monk. So it’s biofeedback, but based on someone else’s optimal brain patterns.
