Emotion and consciousness are the things that make humans different from other animals. Without feelings, there is no point in being a human. Well, we have a misconception that we can only witness the best things by touching or seeing. But that is not something we should consider.
You have to understand the fact that you can observe the best things in the world, even without touching and seeing. All you have to do is to open your heart. Well, you have to acknowledge that different persons have different perceptions of beauty.
Different things will induce different emotions for different people. For instance, some people prefer the vibrant colours of the sky. For them, the sky looks best when it is full of colours. Similarly, some people prefer the sky to be blue and clear so that they can cherish the vastness of it.
Thus, you will find out that there is no standard definition for beautiful. To be precise, beauty is something that you must feel from your heart. So, open the eyes of your heart and witness the splendor of this world. Your eyes of the heart are the best way to savor the beauty of this world.
