from Hindu literature:
"Who knows how it was, and who shall declare
Whence it was born and whence it came?
The gods are later than this creation;
Who knows, then, whence it has sprung?
Whence this created world came,
And whether he made it or not,
He alone who sees all in the highest heaven
Knows—or does not know."
25Rig-Veda, X1 129. (Cf. MacNicol trans.,Hindu Scriptures, p. 37.)
