All connections stem from a single, original living root. Despite all efforts, it's impossible to discern which branch or connection came into existence first.

Imagine a massive tree with countless branches. This couplet beautifully reminds us that despite all these different parts, everything stems from one original, living root. It suggests that once we understand this deep connection, it becomes impossible to tell which branch emerged first, or which part is working harder than the other. All efforts, all manifestations, are ultimately intertwined and nourished by that single, foundational source. It's a profound thought about the unity of existence and the shared origin of everything.
