wordplay - A Rhyming Six-Words Puzzle

In the spirit of the original Four-words puzzle by Prem, and all those that followed.

My first completely overshadows anything you see.
My second's used extensively to mean extensively.
My third are pithy aphorisms commonly dispersed.
My fourth's what you'll be feeling if Deusovi solves this first.

My fifth's predominantly white, though legend says it's golden.
My sixth is what will keep the world consistently unfolding.

My whole's a square that's six by six with letters in each cell.
There is no difference in the words read flat or vertical.
