Principles ?

Principles ? know it, learn it, find a cure for it ?

When faith is tried, and hits hard like crashing tides.
When hope fades, like moonstruck of faining wades.
When peace taken, and refuge sought for an awakening.
When love lost, of purity and honesty, a cure is to be free.
What to know, when truth is bound in similitude.
What to learn, when trust is thrust in the mist of dusts.
What to find, when life is blist in a serpentʻs hiss.
