Compassion and love, that's all.
Our culture's zeal for longevity reveals our incredible collective fear of death.
There are wars and poverty and so on - it's based on fear. You can cure that with your being by not being afraid.
Our journey is about being more deeply involved in life, and yet less attached to it.
In an evolutionary perspective, the rational mind takes a certain distance and no further, & we must be able to transcend it.
Early in the journey you wonder how long the journey will take and whether you will make it in this lifetime. Later you will see that where you are going is HERE and you will arrive NOW...so you stop asking.
