The UK’s “mindfulness mega-trend” shows no sign of running out of breath, with sales of “mind, body, spirit” books booming, against a background of slowing sales elsewhere on the shelves. Topped by Buddhist monk Haemin Sunim’s The Things You Can See Only When You Slow Down, a guide to “how to be calm in a busy world” that has sold more than 43,000 copies this year, sales of titles offering spiritual assistance are up by almost 13.3% in volume in 2017, according to sales monitor Nielsen Book. This sits against a total consumer market drop of 1.6% on the same measure. Rhonda Byrne’s perennial bestseller The Secret is the next-best performer, with 29,000 print sales. Other hits include Eckhart Tolle’s 1999 guide to spiritual enlightenment, The Power of Now, Gabrielle Bernstein’s The Universe Has Your Back, Louise Hay’s You Can Heal Your Life and Dominique Loreau’s L’art de la Simplicite: How to Live More With Less.
