(6-6) The person who knows doesn't die like the person who doesn't know. El que sabe no muere como el que no sabe. Not all knowledge comes from books.
Those who know also have a responsibility to share knowledge with those who don't know. Children are the ones we're most responsible for teaching, but there are many adults who never developed the kind of awareness or consciousness that makes them thinking beings. They go through life in a fog, never putting their thoughts together in a coherent way to make sense out of things. It's not a lack of intelligence but, rather, a lack of concentration and self-discipline that makes them ignorant. They don't learn from past mistakes, they don't take responsibility for their actions, they don't see the consequences of their behavior. They repeat the same error and never understand why it's wrong. Often, these are the people who are the quickest to say "I know" when they don't know. They don't want to listen, they don't want to learn, they're convinced that they "know" and they dismiss people who could teach them something. Their egos won't allow them to be humble and admit they might not know everything, or that someone else might know more than they do. Their automatic defense when anyone challenges their thinking is to say "I know" and, in that way, they avoid an opportunity for learning. Usually, they aren't aware of what they're doing, and don't understand why they're having problems. They don't "know" what they need to know, and therefore, they can't live in a way that's really meaningful.
This refran talks not only about the importance of knowing, or being aware, but also about the importance of being open to knowledge and wisdom others want to share with you. It talks about the responsibility of sharing what you know, and the responsibility of living in accordance with your beliefs, knowledge and experience. In other words, it requires you to be aware and let that awareness guide you through life, so you can walk on the right path and reach your final destiny at the time and place it awaits you.
