Laghu Shanti (लघु शान्ति) is a short peace prayer in Jainism. Here, “Laghu” means small or brief, and “Shanti” means peace. So it is a concise ritual or hymn invoked to seek peace, remove minor obstacles, and bring harmony to mind, family, and surroundings. It is shorter than the more elaborate Maha Shanti ritual.
