We cannot trust the proliferating mind or follow it even at the best of times, but even more so in times of crisis. Proliferation will get us lost in ourselves, losing the outer awareness we need to handle the situation. Worse than this, what we can notice is how the proliferating mind will always take us only in one direction or the other. If we hear news that is worse than we thought, then the proliferation will be negative, dragging us into fear or depression. If the news are better than our current perception, then the proliferation will go the opposite way and we can get over-confident and lose our proper caution.
So we must try to keep establishing our mindfulness which does not believe in the proliferation but continues to remain aware of the outside world.
Then clear thinking in the present as well as meditation will override the proliferating mind.
