"It's a quote from a famous speech and basically, the idea is that true freedom (and implicitly true continuous growth) means keeping yourself open to the possibility that at any moment, what you know, what you think is true or right might change. It means constantly digesting new information, processing new encounters and giving them the power to change little essential things about you. Hanging loose when all you wanna do is hanker down and hold tight."

As I've lived through a solid three decades of adulthood, probably one of the biggest surprises to me is how few adults have the ability to redefine what they once considered to be "truth". I mean we did this constantly as children (Santa Claus or The Tooth Fairy). As we age a lot of people, I would say the majority, loose this philosophical flexibility. Maybe due to fear of the unknown or ego? They would rather die on the hill of their own false beliefs than admit they were wrong and there's a better way. This ability to reframe perceptions becomes absolute necessary if you want to evolve and better your life in any substantial way. I think this is why so few people actually find true freedom. This is one reason I love meditation-- it keeps your mind flexible, open, and also keeps the ego in check.
