Here is the commonly used Laghu Shanti Path in English (translation of the short peace prayer “Sarve Bhavantu Sukhinah”):

English text:

May all beings be happy. May all be free from illness. May all see / experience auspiciousness. May none suffer or be in sorrow. Om, Peace, Peace, Peace.

This short Laghu Shanti expresses the core Jain feeling of ahimsa and universal goodwill – wishing happiness, health, and peace for every living being, and the removal of all suffering.

If you were instead asking for the full Jain “Laghu Shanti Stotra” (beginning with “Santim santi-nisantam…”) in English, that is a longer text; I can share its full English (Roman) lyrics and simplified meaning if you want that version.
