# Heidi — Key Concepts & Themes

> Key concepts in Heidi by Johanna Spyri.

- [The alp and belonging](https://www.betterreads.dev/discover/heidi_se/concepts/alp-and-belonging.md): Heidi thrives with Grandfather on the mountain because freedom, goats, and sky replace the stiff rules that crush her in Frankfurt.
- [Clara's healing and friendship](https://www.betterreads.dev/discover/heidi_se/concepts/claras-healing.md): Clara Sesemann’s wheelchair-bound life loosens when Heidi’s mountain air, goat’s milk, and Peter’s jealousy push her toward walking.
- [Faith and prayer](https://www.betterreads.dev/discover/heidi_se/concepts/faith-and-prayer.md): Heidi’s simple trust in God’s friendliness contrasts with adult despair — especially Grandfather’s thaw and the grandmother’s hymns.
- [Frankfurt versus the mountain](https://www.betterreads.dev/discover/heidi_se/concepts/frankfurt-contrast.md): Miss Rottenmeier’s house teaches Heidi what she lost — and shows adults that children need nature, not only tutors and etiquette.
