With people's growth, why not always called immortal? When I look close, 'tis not a banyan, but a forest.

This couplet asks why something isn't considered immortal when its people flourish. It then offers a beautiful analogy: when you look closely at a banyan tree, you don't just see one tree, but an entire forest of interconnected banyans. This suggests that true immortality or vastness comes from collective growth and expansion. Just as a single banyan spreads its roots and branches to create an ever-expanding grove, the strength and multitude of people can make an entity or an idea eternal and boundless, far beyond its individual origin. It's a profound thought about unity and enduring legacy.
