This sentence is not fully narrated in the original work. In the original work, Heathcliff said similar words about heaven before his death: "——I tell you that I am about to reach my heaven. "Other people's paradise is worthless to me, and I don't care about it." (See Chapter 34 of the original work)

The specific paragraph is: "I am not angry, but very grateful, Nelly. ," said he, "for you have reminded me of the manner in which I desire to be buried, to be conveyed to the church-yard in the evening, if you will, and you and Hareton may accompany me: especially remembering to pay attention to the vicar. My instructions regarding the two coffins will be followed! No need for a priest to come; no need to say anything to me - I tell you that I am about to reach my heaven; other people's heavens are worthless to me. It’s not surprising.”

“What if you persisted in your hunger strike and died like that, and they refused to bury you within the confines of the chapel?” I said, surprised to hear his disregard for God? .

In the movie, this sentence was changed to "Heaven is not my home. After crying and breaking my heart, I want to return to the world." It seems to be more tender. The scene remains unchanged, and I still hope. Clifford said this while lying on his deathbed.
