Hi, can anyone help me solve a Russian riddle, here it is:

"What is in the hands of time, but has no beginning and no end?
Mighty and weak, but timeless in its wisdom.
The answer is hidden in infinity,
O fervent heart, bolder, find its holy place."

The answer could be encrypted and written in any of the languages, or it could be some kind of cipher in which the answer is numbers on the order of 1-2-3-4, etc.
But this is all just speculation, I need your help forchans.
