In prior episodes, Oprah spoke with spiritual thinker Eckhart Tolle, author of The Power of Now and A New Earth: Awakening to Your Life's Purpose, about the power of living in the moment and finding your mission in life. Now, Oprah has invited Eckhart back for a third week to help answer callers' questions about his way of thinking.

How do you embrace "the now" when you're inundated with the mundane tasks of everyday living? How do you deal with family members who refuse to accept your new way of thinking? Eckhart shares his insights on these questions and more.
