“To say this book is a labour of love is a massive understatement. Nidrā Shakti: the Power of Rest is ‘the impossible biography of Nidrā Shakti — the Queen of Sleep and Dreams’, but if anyone can approach such an impossibility it is Uma Dinsmore-Tuli—producing a maven-work that is as gracious as it is detailed. The devotion, thoughtfulness and attention that have gone into this extraordinary encyclopaedia sing from the pages. This is exquisite, erudite and passionate writing — a feast for the eyes, heart and soul. Rest, as Uma Dinsmore-Tuli makes clear, is a radical act in a world in which exhaustion and burnout are commonplace and where human life is routinely devalued from its sacredness to being just another exploitable resource. Nidrā Shakti: the Power of Rest will take you on a journey into the liminal space of lucid sleep where there is abundance, not scarcity; sacred humanity not burnout; spaciousness and healing, not constriction and pressure. In this lavish, generous book you will be welcomed into a world of rest and restoration, remedy and relief. We live in a world crying out for the gifts of ‘return, repair, restore’ and here they is — overflowing with the nurturing, empowering wisdom that the world needs —decolonised, inclusive, replete with the evidence of how yoga Nidrā heals, and brimming with love and creativity. I am in awe of this encyclopaedia—a blessing for all who read it.”

"Uma has made an enormous contribution to the practice and teaching of Yoganidrā. It is a great benefit to Yoga studies that she has documented her vast knowledge, research and experience in his encyclopaedia."
