from “A Guide to the Bodhisattva’s Way of Life” by Shantideva, 8th Century

There is nothing here that has not been explained before
And I have no skill in the art of rhetoric;
Therefor, lacking any intention to benefits others,
I write this in order to acquaint it to my own mind.

(Ch 1.2)

Leisure and endowment* are very hard to find;
And, since they accomplish what is meaningful for humanity,
If I do not take advantage of them now,
How will such a perfect opportunity come about again?

(Ch 1.4)

*དལ་འབྱོར (Dal-‘byor). “This term denotes the perfect condition of human existence, in which one has freedom from eight particularly unfavorable states of being and is endowed with the ten conditions conducive to leading a spiritual life.” – Stephen Batchelor
