The Book of Rest: Stop Striving. Start Being
by James Reeves and Gabrielle Brown
published by Harper Collins
hardback, 234 pages
The authors, both yoga practitioners and teachers for many years now, founded Restful Being, a school for yoga and meditation specialising in yoga nidra, in 2014. Yoga nidra (sometimes referred to as 'sleep yoga') is 'a transformative state of deep rest'.
This book presents many facets of what rest is, and teaches you (amongst ther things) how to actively do nothing, which is harder than it sounds but brings with it enormous benefits to the mind, body and soul.
