"Birds" You can't see your truth, all you see is your shadow. Because this is a very philosophical poem, according to the fact that there are a thousand Hamlets in the hearts of a thousand people, the following is my understanding.

1 You can understand that you are always changing, because you are different all the time, so the shadow you saw before represents you. After all, the shadow has been following you.

You can understand that you are blinded by your own subjective thoughts. Although what you see is not your truth, you can roughly draw your outline because of your understanding of yourself, but it will be biased, just like a shadow, so you can't see your truth. 、

Literally, what you see is your own shadow, even the mirror is just a reflected image, and you can't see your true self.

Or you live in a virtual world and can't find yourself, so you can't see yourself clearly.

It is difficult for five people to understand themselves. No one can fully understand themselves, but they can only see their general outline like a shadow. In fact, people know themselves as well as the world.

The above is my simple view.
