The First President of India Dr Rajendra Prasad, Who is supposed to be the most brilliant, the most scholar President of India, was a theist. He used to like and sing the prayer as written below daily/always the most:-

"sita rama sita rama sita rama kahiye
jahi vidhi rakhe rama tahi vidhi rahiye...
mukha me ho rama nama rama seva hatha me 

tu akela nahi pyare rama tere satha me
vidhi ka vidhana jana hani labha sahiye, jahi vidhi...
kiya abhimana to phir mana nahi payega
hoga pyare vahi jo shri rama jo ko bhayega
phala asha tyaga kuchha kama karte rahiye, jahi vidhi...
jindagi ki dora saunpa hatha dina natha ke
mahalo me rakhe chahe jhopri me vasa de
dhanyavad nirvivad rama rama kahiye, jahi vidhi...
asha eka rama ji se duja asha chhora de
nata eka rama ji se duja nata tora de
sadhu sanga rama ranga anga anga rangiye, jahi vidhi...
kama krodha tyaga pyare rama rasa pagiye
lobha moha tyaga pyare rama nama lijiye"
