It’s really two totally different subjects that may happen to overlap. Considering it will return us to the pre-bronze age and we aren’t prepared for it, I expect a 95% population loss due to reliance on complicated energy based systems. Had we still been hunter gatherers, I would guess that number to be far lower. Now if it’s the full impactor micro nova that is overdue at 12k years, expect 50% dead in seconds, and then the following severe weather for unknown years that will whittle that down to a few percent. As far as enlightening, learn to grow food, make what you need, raise animals that eat grass (grows in all sorts of weather), and have the time to ponder such subjects. The mass awakening of collective consciousness has also been heavily damped down worldwide as a concerted effort, so there’s that.
