"Why Walk When You Can Fly?" uses parables, moving stories, and humour to impart essential truths and help readers find happiness, fulfillment, and peace. At the heart of the Isha System are four 'keys' - simple, powerful statements that can radically transform readers' lives. Using the keys involves repeating them to oneself over and over, with a pause between repetitions. As readers practice the keys, they begin to notice profound changes taking place in their lives and an abiding sense of well-being.The first key involves embracing the present moment; Isha explores the many habits of mind that enforce separation and lead to suffering and introduces this simple key as the main tool for overcoming these habits. Second is accepting what is, without judgment; third is loving oneself and others unconditionally; and fourth is being one with the universe. Isha offers gentle, persuasive guidance, while her practical strategies show how to incorporate the four keys into even the most hectic schedules.
