Shankarachadia says, yashanirakata, the savart masser, whoever denies this pure consciousness awareness is denying it. You don't have to be a non dualist. If you makme the most mitted dualist and a believe and have a simple devotion to god, you can be an atheist. Whatever yo are, whatever our views and ideas and conclusions are that one consciousness is the same for every one of us. We become enlightened brammagani itis. Because of that consciousness alone, it's instantaneous, always shining, all the time, shining effortlessly.
