I very recently started getting quotes of the day and such and found this coincidence amusing and worth dwelling on.
"When you give a shilling to a beggar - do you realize that you are giving it to yourself? When you help a lame dog over a stile - do you realize that you yourself are being helped? When you kick a man when he is down - do you realize that you are kicking yourself? Give him another kick - if you deserve it!" - Why Lazurus Laughed by Wei Wu Wei
From the Buddhist daily thought
"A new commandment I give unto you, That ye love one another; as I have loved you, that ye also love one another. By this shall all men know that ye are my disciples, if ye have love one to another."
The parallels are not direct, but the Buddhist is in a way justifying this golden rule. You help these others, you don't kick them, you love them because how you treat others is not only a reflection of who you are, but we're all in this together, all connected, and it's gonna come back to you somehow. So pay attention, be aware, be mindful of these instances in our daily lives, these passing moments - they are not just your moments, you're sharing them with others, so love them for it.
