For deep sleep, light sets the stage, @christopherstone, but sound's the star.

Christmas lights and fog machines are a classic fire combo. Grab a fused power strip next time, stops things from melting. Learned that after my own near miss with some cheap LEDs.

Yeah, that's a really solid way to handle it. It goes beyond just feeling weird and turns into a real filter for quality. A guide that explains the "why" behind a practice usually shows the teacher actually understands it, not just copied the sounds. I've started looking up teachers to see if they have real training in the tradition they're teaching. It cuts out a lot of the shallow, take-what-sells stuff. Makes your practice way more grounded when you know it's not just taking from a culture without respect.
