तुका म्हणे विंचु सर्प नारायण, वंदावे दुरोन शिवो नये - संत तुकाराम

We know that God is equally present in all living entities. So we must love and respect all the living entities.
In this case, if we come across a person who is difficult, having bad habits or is trying to disturb/distract our path, how to handle such a person. Tukaram Maharaj explains beautifully in the below Abhang:

जन देव तरी पाया चि पडावे | त्याचिया स्वभावे चाड नाही ||१||
अग्नीचे सौजन्य शीतनिवारण | पालवी बांधोनि नेता नये ||२||
तुका म्हणे विंचु सर्प नारायण | वंदावे दुरोन शिवो नये ||३||

As God is present in all the people, we should pay our respects to them, but should not keep dealing with them if we are not able to handle them. We cannot change anybody's nature easily, we should rather stay away from such a person.
Fire is very beneficial to us, in that, it saves us from cold. But if we put tender leaves of the tree in the fire, they'll surely get burnt. Here, tender leaves do not have capability to handle the fire (which in itself is not bad), hence they are expected to stay away from fire.
He further says, God is also present in snakes and scorpion, hence one should respect them but should not go and touch them.
This is the way to handle difficult people, if you cannot manage them, stay away from them!
