Having a visual sometimes helps.
When reading scripture I like to visualize it.
I would like to be as accurate as possible.
If we went back in time to the moment Moses said "Hear O Israel", and were present there, what would it have been like?
Not just where he was standing, but what was around him? A camp fire? Was it near a mountain? Could they hear running water if a river was nearby?
So that I can memorize is my purpose, write it on my heart if you will.
(The stated goal of the question is to aid in remembering Torah. But perhaps visualizing Torah is an incorrect way of going about this; could singing the Torah be a better solution?)
Visualizing it as I was actually there is the goal.
Not visualize it being written down, but visualize what's being wrote down.
