The One remains, the many change and pass;
Heaven's light forever shines, Earth's shadows fly;
Life, like a dome of many-coloured glass,
Stains the white radiance of Eternity,
Until Death tramples it to fragments.
I believe compassion to be one of the few things we can practice that will bring immediate and long-term happiness to our lives. I'm not talking about the short-term gratification of pleasures like sex, drugs or gambling (though I'm not knocking them), but something that will bring true and lasting happiness. The kind that sticks.
A child can teach an adult three things: to be happy for no reason, to always be busy with something, and to know how to demand with all his might that which he desires.
