Let the gentle bush dig its root deep and spread upward to split the boulder.

The image contrasts apparent weakness (“gentle bush”) with the slow, cumulative force of persistence. By rooting “deep” and growing “upward,” the plant embodies patient endurance and organic growth rather than sudden violence; yet over time it can “split the boulder,” a symbol of entrenched obstacles, institutions, or despair. Read as Sandburgian in spirit—sympathetic to common, unheroic forms of strength—it suggests that steady, grounded effort can overcome what seems immovable. The line also implies a moral: power need not be loud or harsh; resilience and time can be transformative forces.
