I believe that this quote is also true in a broader sense. We cannot simply teach someone something by telling them about it. They need to be actively involved in the learning process, and they need to discover the knowledge for themselves. This is why it is so important to create opportunities for students to explore and experiment, and to ask questions. Learning is not a passive process, and it requires effort and engagement.
When we help someone to find the knowledge within themselves, we are not only teaching them something new. We are also helping them to develop their own critical thinking skills and their ability to learn. This is a gift that can benefit them for the rest of their lives.
