What need is there to say more? The childish work for their own benefit, The Buddhas work for the benefit of others. Just look at the difference between them.
ShantidevaOne should do nothing other than what is directly or indirectly of benefit to living beings.
ShantidevaUnruly beings are as unlimited as space They cannot possibly all be overcome, But if I overcome thoughts of anger alone This will be equivalent to vanquishing all foes. Where would I possibly find enough leather With which to cover the surface of the earth? But (wearing) leather just on the soles of my shoes Is equivalent to covering the earth with it. Likewise it is not possible for me To restrain the external course of things; But should I restrain this mind of mine What would be the need to restrain all else?
Shantideva
