"Meditation, unlike commonly thought of, is not about "emptying your mind" or "getting in tune with the Universe". Meditation is all about letting a thought, concept or idea completely soak your brain."
I'd need to see sources to back this up. It's completely the opposite of everything I've read about meditation. You're neither supposed to hold on or actively attempt to push out any given thought while meditating.
For me I found that meditation helps concentration, sleeping and helps me to not cling to the various negative things my brain throws at me on a daily basis.
