TEDx events use the TED conference format but are independently organized by a local community. Usually they are excellent talks, 10 to 20 minutes in length. I recently found 3 about mindfulness that I thought provide a useful views of practice and ideas about how and why to practice.

Eilona Ariel is a documentary filmmaker whose work was deeply inspired by her life in Asia and her practice of the ancient meditation technique called Vipassana. Vipassana or Insight Meditation was what I studied with Gil Fronsdal in California (see Insight Meditation Center) in the 1990s, and today it's typically referred to as mindfulness meditation. Eilona was trained in the S N Goenka method which she refers to here. It has had a big impact on the world (see Wikipedia):
Goenka (1924 - 2013) trained about 1300 assistant teachers to conduct courses using his recordings, and about 120,000 people attend them each year. Upon Goenka's death, Jack Kornfield, noted American author on Buddhism wrote, "In every generation, there are a few visionary and profound masters who hold high the lamp of the Dharma to illuminate the world. Like the Dalai Lama and Thich Nhat Hanh, Ven. S.N. Goenka was one of the great world masters of our time. [He] was an inspiration and teacher for Joseph Goldstein and Sharon Salzberg, Ram Dass, Daniel Goleman, and many other western spiritual leaders." Jay Michaelson wrote in a Huffington Post article titled, "The Man who Taught the World to Meditate", "He was a core teacher for the first generation of 'insight' meditation teachers to have an impact in the United States."
