Here's a simple Jainism-focused description:

• Panchmeru (five Mount Meru peaks) is the central cosmic mountain in Jain cosmology. It is the axis around which the universe is organized and sits at the center of the Jambudweep region in the middle loka (the earthly/middling plane).

• The three lokas (tripiṇḍa) are:

- Urdhva-loka (upper world/heavens) - Madhya-loka (the middle world, where humans live) - Adho-loka (lower world/hells)

A basic “3-lok” map would show Mount Meru and Panchmeru at the center of Madhya-loka, with realms of Urdhva-loka above it and Adho-loka below it, and the various continents (like Jambudvipa) arranged around the axis in Madhya-loka.

If you’d like, I can help locate a JainKnowledge page that has a diagram or a more precise layout and explain any differences between Digambar and Shwetambar presentations.
