Of all the ways we have found to hurt ourselves, the worse has been through love. We are always suffering because of someone who doesn't love us, or someone who has left us, or someone who won't leave us. If we are alone, it is because no one wants us.
When one drives away the negligent through vigilance, he climbs the heights of wisdom, and can see the suffering masses. Serene, you look upon the lost like one that stands on a mountain sees those that stand upon the plain.
Now this, monks, is the noble truth of suffering: birth is suffering, aging is suffering, illness is suffering, death is suffering; union with what is displeasing is suffering; seperation from what is pleasing is suffering... in brief, the five aggregates subject to clinging are suffering.
If there is suffering, then it's best to accept it, because it won't go away just because you pretend it's not there. If there is joy, then it's best to accept that too, even though you're afraid it might end one day.
