Meaning: It is easy to imagine an impressive plan without providing what would make it real. Castles in the air picture ambition without foundations, asking what practical support the idea needs rather than condemning imagination itself.

Meaning: Distance may weaken a mild attachment while making an intense one feel stronger. The contrast between cooling and inflaming describes different possible responses to absence, rather than a dependable rule for measuring love or deciding how relationships should work.

Meaning: What someone feared may have been worse than what actually happened. The comparison can bring perspective after an event, without deciding in advance that a concern is groundless or dismissing the distress of being frightened.
