Many Binurials could be easily found on Youtube. It is a mere search away! Whether it is good or not , one can easily find out from personal experience , comments , views and Likes. It is so easy to find. Just search it!
You can play the Binurial during your meditation and contemplation on that psychic centre , or you can just lay down and relax while listening to them. If that is the case , accidentally falling to sleep is fine in my opinion.
However you choose to use them , the effects are still there.
