Sometimes you do all the right things and still - for some reason - suffering sneaks in. It happens.
The alleviation of suffering is not totally possible. The limiting of suffering, however, is. I struggle to limit the suffering. Suffering in my own life and that of others. I do not succeed all the time. It happens.
Doing the right thing is the first step towards removing suffering. Will we ever get there? likely not. But we can make steps towards that goal.
