Thanks for sharing Emma J.
TWR has been my teacher for years now. To be clear, it's not that sleep and wake awareness merge--what is cultivated is a continuum of awareness, at all times. There aren't many traditions that teach this. Only recently have sleep and dream yoga, as well as dark retreat, begun being offered to students. Traditionally, these practices have been kept "secret", or at least only taught once the student has become sufficiently advanced. One must be securely grounded before attempting these practices. However, they are being slowly revealed today because the times seem to require going beyond materialism.
Also, fostering sacred sleep affords all the other positive healthful changes.
It’s so interesting. I’ve never heard of dream yoga, dark retreat or a continuum of awareness… there’s so much to learn!
Each new learning brings more ... that's why it's called "lifelong learning" :)
Take your time though. When you're ready the new material presents itself.
