And, indeed, I will at this point ask an idle question on my own account: which is better — cheap happiness or exalted sufferings? Well, which is better?
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.
Those who recognize the existence of suffering, its cause, its remedy, and its cessation, have fathomed the four noble truths. They will walk in the right path.
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.
The rationale for loving others is the recognition of the simple fact that every living being has the same right to and the same desire for happiness, and not suffering, and the consideration that you as one individual are one life unit as compared with the mulititude of others in their ceaseless quest for happiness.
