There's a 22-minute audio designed by Jose Silva in the 1960s. Listen to it once, and your brain learns the path to alpha: the brainwave state where the body accelerates healing. The audio was originally given out at $400 seminars. Wall Street executives, athletes, and doctors took those seminars. Once you'd done the 22 minutes, you could access alpha anywhere, anytime: with a simple finger movement. Now Vishen Lakhiani teaches the same method free. 6 million people have used it for healing, sleep, stress, and pain. Free 35-minute masterclass with Vishen Lakhiani.
Not enough history yet to show a trend.
