Standing firm and not looking back

Meaning

The repeated prohibition on looking back accompanies the First Response's terrifying signs. The recipients are first told not to recoil from what meets them; after the wind and beasts they must stand firm, and after the earthquake the injunction returns. Repetition makes constancy a condition of continuing the narrated journey. It does not mean the treasure is already available: the response expressly says that the wind's destruction has not yet laid it bare. The guide's promised protection supports perseverance, while the lack of bodily weapons distinguishes this posture from a command to fight the beasts physically.
