Whether we like it or not, we have all been born into this world as part of one great human family. Rich or poor, educated or uneducated, belonging to one nation or another, to one religion or another, adhering to this ideology or that, ultimately each of is just a human being like everyone else. We all desire happiness and do not want suffering.
There's nothing wrong in suffering, if you suffer for a purpose. Our revolution didn't abolish danger or death. It simply made danger and death worthwhile.
When the suffering of another creature causes you to feel pain, do not submit to the initial desire to flee from the suffering one, but on the contrary, come closer, as close as you can to her who suffers, and try to help her.
