Naan Unnodu is based on Isaiah chapters 41, 43:2. I will always be with, you will never be forgotten. I thought of you, called you by name, engraved you in my palm, and will not forsake you. First verse goes : Do not be afraid, I am by your side, don’t be dismayed, I have befriended you. I am your God, you are my servant, I will uphold you with my right hand of righteousness. 2^nd verse goes : you shall cross waters but not be drowned, you shall walk on fire but it will not burn you. (Isaiah 43:2)
