I'd like to analyse this passage bit by bit and give some reflections I had on it. I'll begin:
"Formerly, I, Zhuang Zhou, dreamt that I was a butterfly, a butterfly flying about, feeling that it was enjoying itself. I did not know that it was Zhou."
Zhuangzi himself details an experience where he dreams of being a butterfly that is enjoying itself. Throughout the whole Zhuangzi text, there is this motif of enjoyment. The image of a butterfly happily fluttering about is very evocative.
"Suddenly I awoke, and was myself again, the veritable Zhou. "
He wakes up, as the "veritable" Zhou. As in, the real deal. Or is he?
"I did not know whether it had formerly been Zhou dreaming that he was a butterfly, or it was now a butterfly dreaming that it was Zhou."
Perhaps it is the case that both are true, or neither!
"But between Zhou and a butterfly there must be a difference."
Zhuangzi and the butterfly seem to be interconnected in this instance, dreaming of one another. Yet, they are 2 distinct experiences.
"This is a case of what is called the Transformation of Things.' "
This "transformation of things" might be the most mystic passage in the Zhuangzi text's most esoteric chapter. It is the final passage of this chapter, and the capstone on its many reflections.
This "transformation of things" is a suggestion that in a sense, there is more than meets the eye. It hints at the possibility of other realities that are connected yet distinct from our own, by questioning if the dream of being a butterfly was the true reality, and characterizing the dream as a distinct reality from the waking state of Zhuangzi.
But what are dreams really? To this day science hasn't came up with a convincing answer to that question, and it's a bit of a mystery. However, one can observe some aspects of dreams from our own experiences, and allow me to make some observations here:
Dreams can contain aspects of things you have seen and can remember seeing; people, places, and things.
However, dreams can also warp these familiar elements enough for them to be uncannily different. For instance a familiar environment can be turned topsy-turvy, re-arranged, re-scaled, made more more vertical, and so on. People say or do things they wouldn't do in real life.
There can be fantasy aspects to dreams, such as magic and places out of fiction.
There are also forms in dreams which appear to be uniquely from that dream, although they may just be a mishmash of associations, some of which we do not even consciously remember.
-Dreams often reflect on and reference our psychology, such as fears and hopes. They also seem to draw from our imagination, and from things we have seen both real and fictional.
There is much art based on dreams, and many dreams based on art. And what is the commonality between dreams and art? Both serve as conduits for the imagination, dreams unconsciously and art consciously. And what is imagination? It's something entirely new, coming from our minds. Imagination is the creative force in our intellect, and dreams channel from it directly, fusing it seemlessly with snippets from our conscious memories. Art also channels directly from our imagination, and our imagination mixes from what we experience in order to make art. Much of art fuses imagination and lived experience to reflect on various aspects of life's journey.
Zhuangzi often mentions that we should seek to just enjoy life in ease rather than worry about the "best" way to live. Now what are some of our most common sources of enjoyment? Music, stories, movies, paintings, and video games. These are products of our creative force, our imaginations. Zhuangzi encourages us not to rigid so that we may enjoy life, therefore it is worth reflecting on the things that do bring us enjoyment. Notice how he said that in the butterfly dream he was enjoying himself. He questions if he is a butterfly dreaming he is Zhuangzi, implying the dream could be its own distinct reality which is connected yet seperate from his life as Zhuangzi.
Now, what else brings us enjoyment and is connected yet seperate from our lived experience? Art. Art is derived from our pure creative force of imagination. And yet often enough, it is relatable. It says something about life, almost like a reflection of some aspect of it albiet, more symbolic. And in this sense, art, imagination, and reality are inextricably linked. And where do all of them converge? Dreams. Art, dreams, and imagination bring us enjoyment, are spontaneous and freely associated to everything internal and external, and are infinitely varied. They represent the chaotic jumble of the Dao in a sense, and the way they interact and change with eachother is the "transformation of things" Zhuangzi is hinting at. We often forget our dreams, and if we didn't take the time to make art we often forget what we imagine. It is constantly changing, much like the Dao.
And by suggesting that in fact, the dream could be the actual reality, or that both could be reality, Zhuangzi is suggesting that they are all associated and have potential to be distinct realities of their own, which interact with and compliment eachother; these things give us enjoyment and allows us to reflect on the many facets, aspects, archetypes, forms, and dimensions in our experience. If rigid ideology and fixed viewpoints are what Zhuangzi suggests we take our focus away from, these things which relate to the imagination and experience seem to be the "good stuff", which makes our "free and easy wandering" all the more enjoyable.
By ending chapter 2 in this manner, he gives a closing statement which substantiates exactly why we shouldn't be so attached to what we think is true; there is more than meets the eye, and it is often beautiful, imaginative, awe-inspiring, mysterious, and enjoyable. But in order to have these things, we need to be looking on the moment with clarity, unburdened by what we think we know.
