Windows or sometimes entire building fronts are made of glass today. This has the effect that the rooms behind them become very bright, depending on the size of the glass surface. On the other hand, when viewed from the inside, large glass surfaces offer a wider view, a broader horizon, so to speak. In short: the more transparency, the more light and brightness and view. Always on the premise that the glass is not dirty or clouded. Jesus once makes a similar comparison with the eye and says: if your eye is clean, then so is your whole interior. So for me: if there is a large, clear surface of glass - the eye - then I also feel more comfortable inside - it is brighter - and from the inside I also see better, purer and more to the outside - instead of only my own inside. I find this comparison with the eye remarkable. How we see our environment and ourselves has a massive and concrete impact on our attitude, our inner being, our actions and thinking.
