This is why Dzogchen is a ‘short cut’ compared to other Buddhist teachings, because liberation isn’t only about resolving emotional & psychological obscurations (however these naturally begin to dissolve by themselves via the Dzogchen methods); it’s also about preparing for death so that when the death process begins, you know what to look for, and if you recognize it, whatever emotional & psychological obscurations you’re still carrying within will dissolve all at once in the Bardo, and you attain total liberation right then and there.
