What does the Vatican Palace mean in the poem?

I didn't understand the second sentence at the end of the study.

But the first sentence has a deep meaning. Nowhere else in the west, it is now.

There is a cloud: chanting Buddha means that when you recite Amitabha, you are doing the right thing, and having Amitabha in your heart means mindfulness. Then at that moment, your heart is Buddha's heart.

Then there is no difference between the west and now, that is to say, when you read Amitabha, now it is the western paradise, and you correspond to Amitabha. It seems abstract, but it's true. It's just that we ordinary people don't have a clean heart and can't understand it.

There was a mage who was obsessed with Buddhism and saw that his room was closed and all the walls were gone. He only saw the beautiful scenery of the western paradise, and so did Amitabha. This is the realm, and the present is the west.
