"Tu Prabhu Maro" is a popular Jain devotional song (bhajan) expressing deep devotion and surrender to the Lord (Prabhu). Here is a simple English translation of the essence of the bhajan:

Tu Prabhu Maro (You are My Lord)

You are my Lord, my only refuge, You are my True Support, You are my shelter in joy and sorrow, Without you, I have no one else.

You are my hope, my only guide, You are the light in my life, You are my protector, my savior, You are my everything, O Lord.

I surrender my mind, body, and soul to you, Please accept me at your feet, You are my Lord, my only refuge, You are my True Support.
