Through the Light of Depression

The person called "Tathagata" can only be seen by Changchang. He talked to "Tathagata" late at night, and "Tathagata" said "there is light over there", but there was nothing outside the window. It wasn't until he got sick that I saw the words on his phone that he had deleted and typed, and I saw a recording he made to himself at two in the morning - it was cut off mid-sentence. I tried my best to drive away "Tathagata" and exhaust everything, but I didn't know if it was of any use. All I know is that when he walked out, the light didn't fall from the sky. It is through walking that light comes.
