Thinking “If you’re good then I’ll be good” actually implies “If you’re not good, I will be bad”. This is really a frightful attitude.
A truly virtuous person is one who remains virtuous regardless of how others behave.
(Shwe Oo Min Sayadaw)
Our actions are invariably based on liking (lobha) and disliking (dosa). If we stay aware of the quality of our mind every time we act, then we are like ‘a virtuous person who remains virtuous regardless of how others behave’.
