you are here by thich nhat hanh
"The Buddha said, " The past no longer exists, and the future is not yet here." There is only a single moment in which we can truly be alive, and that is the present moment."
Thich Nhat Hanh is a Buddhist Monk and spiritual leader, once nominated for a Nobel Peace Prize.
This is far the most religion-focused book on mindfulness I have read, but it still contains some wonderful practical lessons. If you are in need for a midweek reset, this book is a great tool to carry with you.
