The plumb line is the simplest beginning.
A weight hangs from a line. Gravity pulls it true. The builder does not invent vertical. The builder discovers it.
The plumb does not argue.
It does not drift with opinion.
It does not ask what looks correct.
This is the first lesson:
Before anything can be built correctly, it must have a reference.
These are not identical systems, but they share a common pattern.
Something is disturbed.
A reference is found.
A correction is made.
The system returns closer to order.
Some systems return to center on their own. Others require attention.
In physics, alignment follows fixed laws.
In practice, alignment is maintained through tools.
In life, alignment is something you choose.
