In Jainism, Lagu Shanti Tapasya (also spelled as Laghu Shanti Tap) typically refers to a type of austerity or penance performed for 10 days. During these 10 days, the devotee follows specific rules of fasting, spiritual practices, and self-discipline to seek inner peace and purification.

However, practices may vary slightly across different Jain communities and traditions, so it is always best to consult with your local Jain monk (sadhu/sadhvi) or community elders for precise observance details.
