If you are angry you will share anger, if you are greedy you will share greed, if you are full of lust you will share your lust. We can share only that which we have, we cannot share that which we don't have. This has to be the fundamental thing to be remembered; hence the first step is meditation and the second step is compassion.
Be advised; Heat not a furnace for your foe so hot That it do singe yourself: we may outrun, By violent swiftness, that which we run at, And lose by over-running. Know you not, The fire that mounts the liquor til run o'er, In seeming to augment it wastes it?
Let us work without desire for name or fame or rule over others. Let us be free from the triple bonds of lust, greed of gain, and anger. And this truth is with us!
