Our brains and parachutes work in the right direction only when both are open. Otherwise both seem redundant. In fact, our brain is a storehouse of knowledge. But we find out when we use our brain properly. A small child who comes in this world with an empty brain. But gradually as he learns, his brain capacity develops. If he is left in the jungle like Mowgli, then surely a mindless brain will form. So always keep your brain open. Use as much as possible so that it works in a meaningful direction.
stay safe and happy
