kimekaṃ daivataṃ loke kiṃ vāpyekaṃ parāyaṇam |
stuvantaḥ kaṃ kamarcantaḥ prāpnuyurmānavāḥ śubham || 2 ||

"Yudhishthira said, "Who may be said to be the one god in the world? Who may be said to be the one object which is our sole refuge? Who is he by worshipping whom or hymning whose praises human being would get what is beneficial? What religion is that which, according to thy judgment, is the foremost of all religions? What are those Mantras by reciting which a living creature becomes freed from the bonds of birth and life?'
