I’ve been reading a book called ‘Yoga Nidra‘ and there is a lot of interesting ideas in it. I’ve learned that what I used to think of as ‘letting my mind wander’ as a child, is actually an ancient yogic practice, and is really a spontaneous activity of the relaxed mind. The images and visions are called ‘samskaras.’ That sounds correct and appropriate somehow.
It’s a good book. It is scientific in it’s explanation of how the yogic practice affects the body, nervous system, etc. It also recommends many practices that I had developed on my own, but didn’t know they were so well documented. Like visualizing the day at the end of it, to help ease into Yoga Nidra, and other techniques.
It’s available on archive.org for free and I highly recommend it.
