Man is like a bead,

In that we should allow for the truth to enter us through the smallest gap possible, as to allow only the truth in.

Like a bead with a hole just barely wide enough for the string to enter, such is the best form. To hollow yourself out unnecessarily or incorrectly is not the right choice.

Luckily, as biological beings, we are capable of self-repair. We can at any point choose to form ourselves differently and to become optimal. And we know that the most valuable diamonds aren't flawless.
