Poetry feeds my soul. Poetry is comforting and soothing, and it's awe-inspiring as a glimpse of rainbow, which should come as no surprise since poems and rainbows have something in common.

VOA: special.2009.10.12

The rainbow is set up as a symbol of the eternal covenant, a token of the eternal reconciliation between the divine and human realms.

彩虹，作为契约生效的标志,标志着神与人之间的永久共存。
