Can anyone help identify this verse?

Hi Everyone,

I'm having trouble locating a verse which, in translation, is
something along the lines of: From darkness to light, from decay to
undecay, from death to immortality, I lead by dhamma.

It includes stuff like:

andhakaarato aalokassa
...... ........
...... amata.m (amatassa?)
dhammena nayaami

Does this ring a bell anyone?

thanks for any tips,
