Jainism ke anusar, Shetrunjay tirth ka uddar (punarudhar ya nirmaan) Raja Siddhraj Jaysinh ke samay hua tha, lekin jhalti hui diya ki vat (batti) le jaane ka prasang Raja Kumarpal se juda hai.

Kahani ke anusar, Jain Acharya Hemchandra Suri ki prerna se Raja Kumarpal ne Shetrunjay tirth ka punaruddhar karvaya tha. Jab Shetrunjay tirth ka nirmaan poora ho gaya, tab Acharya Hemchandra Suri ne Kumarpal ko kaha ki akhand diya (deepak) ki jyot le jaakar tirth par sthapit karein. Kumarpal ne apne mantri Udayan ko yeh kaarya saupa tha. Mantri Udayan ne jalti hui diya ki vat (batti) lekar Shetrunjay parvat par jaakar deepak prajvalit kiya tha.

Is prakar, Shetrunjay k uddar mein Raja Kumarpal aur unke mantri Udayan ka vishesh yogdan tha.
