¿Is it safe for children and teens to use this kind of technology? I,m thinking on the Optimal Learning for instance. Introducing children in the technics of meditation could also be an advantage for them in many ways. I´ve been a self-taugth person in meditation for about a year and I´d love to bring the benefits of meditation to my kids, but I am a little afraid of it. I´d would appreciate any advise about the subjet.
