This is one of those books you want to keep in your purse, bag, car, any place that you can grab and read when you have some down time. Just turn to any page and there is food for thought, spiritual reminders, and wisdom waiting for you. It is thin and compact enough to take with you. One of the things I love about Swami Vivekananda's books, Hindu and yogic philosophy in general, is that these truly are ways of living your life that ANYBODY can follow, which lead to inner happiness, and not temporary happiness, but true freedom and joy. So, there is no limit to the times you can read it, because as humans we very easily forget, we easily get caught up in the mundane and insignificant, so having something you can read to remind us of what really matters helps us to evolve on a frequent, if not daily basis. This is the essence of spirituality.
