"The Power of Now" by Eckhart Tolle, is a self-help book that encourages readers to find inner peace by being fully present in the moment. It emphasizes that the mind, with its incessant thinking and focus on past and future, is an obstacle to experiencing true happiness and enlightenment. Tolle argues that by becoming aware of and disidentifying with our thoughts and emotions, we can connect with our true nature as a timeless, formless, and indestructible being. He presents various practices, such as inner body awareness and meditation, to help readers access this state of consciousness and experience the power of the Now. The book highlights the role of acceptance, surrender, and forgiveness in transcending suffering and fostering inner peace.
