Gamaliel's principle is a fancy way of saying that sometimes, it's better to wait and see what happens before taking action.
Let's say you're playing with blocks and you want to build a tall tower. You start stacking the blocks up, but soon you notice that the tower is wobbling and might fall over. If you keep adding more blocks, it's only going to get more unstable and fall down. This is where Gamaliel's principle comes in.
If you stop and wait for a little bit, you might notice that the tower settles and becomes more stable on its own. This is the principle of waiting to see what happens before making a decision. It's like when a teacher tells you to look before you leap.
Gamaliel was a wise man who believed that patience could be a great asset in life. Sometimes, rushing to make a decision or take action can end up causing more harm than good. But if we take a step back and observe the situation, we might find that things work themselves out on their own.
So when you're playing with blocks or faced with a tough decision, remember Gamaliel's principle and take a moment to observe before acting.
