Thoughts when I read Kundera

Have you wondered what the waves would look like if you really do see them with your naked eyes. The sound waves propagating over to you, seeing the person's mouth move and the waves coming to you, hearing the words milliseconds later and your words, like waves propagating back. Is that what words are? Waves of connection going back and forth never ending, constant and therefore reliable. 

What about the other waves we would see. The electromagnetic waves, waves, rays, light and darkness, light and weight. Everything that is light seems so good but could the lightness be one day unbearable due to the emptiness it brings? If zen is what some seeks, doesn't void brings about a crushing weight of emptiness? Doesn't weight in contrast brings about lightness when one eventually gets used to it, when one learns to deal with it, when one gets stronger it's not longer heavy or burdensome. I've seen some people trudge along the roads with difficulty, some elderly walking slowly, their backs hunched over. I wondered about the lives they had before this. Were they crushed by the unbearable lightness of being or the unbearable weight of life. If we are seeking a balance from all of life, I don't think it's knowing if we seek lightness or weight, I don't think it's about looking at a glass knowing it's half empty or half filled. I think there is no such balance until life ends, and then just like how the dead can never bring away anything with him, he would leave the weight and emptiness all behind.
