Not everyone receives the key to the treasure, because God never reveals divine mysteries to a shallow or petty person.

Here, the 'key to the treasure' serves as a tender metaphor for spiritual enlightenment and the deeper truths of existence. The poet reminds us that the Divine does not reveal sacred mysteries casually to everyone; such wisdom requires a spacious soul. Those who are shallow or petty simply lack the depth and character to carry the weight and grace of divine secrets.
