Let the fool think whatever he will,So easy to read. So hard to do.
In cultivating the highest goal
Nothing compares to patience.
And the highest form of patience
Is to tolerate the weaknesses and shortcomings of others.
Samyutta Nikaya I.222
Nothing throws me back into self-other land faster than losing patience with someone doing or not doing something fast enough, well enough, properly enough, efficiently enough, etc. Nothing.
Śāntideva was right: lose patience, and all attainment, all insight, all keeping of the precepts is lost in an instant.
I should be better than that. I really should. It kills me that I'm not. It's utterly shameful, when you get right down to it.
