You should treat every person with whom you come in contact with the same care as the person you love the most.
Anytime there is a problem in a relationship, you should first see it as your own fault. Even if others are to blame, you will only add to the problem by considering them to be at fault.
Treat each person with the bhakti and care as if the success or failure of your own spiritual life depends on this. Do not take into concern how they treat you.The manner in which you treat people is the same way you treat Guru and Krishna.
Humility does not mean to think yourself less, but to less think of yourself.
