No. The height of Shatrunjay (the hill near Palitana) is not changing second by second. In Jain cosmology and natural science terms, mountains are considered permanent features on a much longer timescale. What you might be noticing are normal observational effects—like clouds, weather, shadows, or perspective—that can make it seem different at a moment, but the physical height isn’t fluctuating moment to moment. If you’re curious about Jain explanations of geography or sacred hills, I can share more specifics from the scriptures.
