- Typical Contexts: Relationships (friendship, love), tests of character, professional challenges, political decisions, ethical dilemmas, quality control.

📜 Poem about the Touchstone
Ein Weg erscheint, voll Zweifel, schwer,
Ein Prüfstein liegt, was willst du mehr?
Er testet Mut und auch den Sinn,
Zeigt, was verborgen tief in dir drin.
Ist echt das Gold, das glänzend scheint?
Ist wahr die Kraft, die sich vereint?
Der Stein gibt Antwort, klar und rein,
Am Prüfstein zeigt sich's wahre Sein.
A path appears, full of doubt, severe,
A touchstone lies, what more is here?
It tests the courage and the sense,
Shows what lies hidden, deep, intense.
Is real the gold that brightly gleams?
Is true the strength that joins in teams?
The stone gives answer, clear and pure,
By the touchstone, true being is sure.
