Cherag Shah uses the metaphor of a sponge to explain how your internal emotions shape your reactions. What's inside you will always find a way out, whether that's anger or clarity.
So depressed only because you want to be depressed. Just imagine a sponge. It is soaked with water. You press, it comes out. It's naughty. Not coffee, nothing but water. Why? Because it had water in it. Imagine your mind if it's soaked with anger, guilt, doubt. Life will press you. Life will throw you challenges. What will come out is that same anger, guilt. It's not because of someone else. It's because that is what was inside you. So next time you want to soak yourself with clarity, with purpose, with belief. Because now when life throws you a challenge, life throws you a hard ball and it presses you, guess what is going to come out? It's going to come out with that calmness, that peace, that belief. And every time when you see yourself with the knowledge around, soak it in because that is what you are going to replicate outside in the world.
