How to understand the poem of sitting close to the sky and sending flowers in the air?

The poet who wrote this poem always looks forward to the scenery of Chang 'an and his understanding of Buddhism with the temple pagoda. The whole poem can be divided into two layers. The first layer is the first triple, which describes the poet's yearning for Chang 'an, a prosperous and peaceful atmosphere. The second layer is the post-Sanlian, the poet's perception of Buddhism. Buddhist allusions are widely used in the whole poem, which reflects the poet's love and understanding of Buddhism.

The first six sentences of this poem describe the scenery of Chang 'an through what the poet saw when he boarded the tower. On both sides of the Weihe River, surrounded by bamboos, the mountains and rivers are bright. Shangyuan stretches continuously, leading directly to the distant mountains. The suburbs of Beijing are full of luxurious mansions of emperors and generals; Tian She, a farmer, is naturally scattered in criss-crossing villages. In the eyes of the poet in mid-air, all this is an equal ornament on the earth, like a variegated fragrant flower in full bloom.

As a result, the poet's further understanding was aroused. Buddhism pays attention to from the first place to the favorite place to the seventh place. It must be robbed by a big monk, and from the eighth place to the Buddha, it must be robbed by a big monk. So say: "tired robbery from the beginning." "Picking sand for children's memory" is translated from "Hokkekyo convenience goods". "Even children's play, picking sand for pagodas, and so on, have all become Buddhism." What I'm talking about here is that boys pick sand and plant Buddhism from afar, which further shows that it takes infinite efforts to become a Buddha. More subtly, these two sentences are related to the tower. It is self-evident that teenagers gather sand to make a tower, but the sentence "the first place" can be extended to mean that the tower is formed from the first place no matter how high it is. The two sentences are not only related to the tower, but also related to the topic, and there are Buddhist principles, and the idea is very clever.

"A glimpse of public morality will increase your heart." The poets here began to tell the story of the Bodhisattva for the first time, and their merits were in the front and then more refined, in order to achieve a complete Buddha fruit.

There is a connection at the end of the poem, not only because we are in the tower and "sit close to heaven", but also because of Buddhism, we can feel the joy of heaven and consciously approach it. The last sentence, "Empty fragrance drives flowers away", secretly uses scattered flower allusions, which highlights his devotion to Buddhism and makes the whole poem end in a magical and beautiful atmosphere.
