Toughest & best thing I do for myself: Twitter CEO on finishing 3rd vipassana

Twitter Co-founder and CEO Jack Dorsey on Sunday tweeted that he has finished his third 10-day 'vipassana', one of the most ancient techniques of meditation, at Dhamma Pataka in South Africa. "(It) continues to be the toughest and best thing I do for myself," he tweeted. Last year, Dorsey did a 10-day silent vipassana meditation in Myanmar for his birthday.
