Chapter 6 Dhyana Yoga Verse 4

Suhrinmitraary udaaseena madhyastha dweshya bandhushu;
Saadhushwapi cha paapeshu samabuddhirvishishyate.
He who is of the same mind to the good-hearted, friends, enemies, the indifferent,
the neutral, the hateful, the relatives, the righteous and the unrighteous, excels.
In this sloka Lord Krishna switches his attention from the person in Nirvalpka yoga to the person who excels in life. Probably this is the first thing that a person needs to do in his journey to salvation. He says that a person who is having a same mind for the good hearted and friends and has the same mind while dealing with enemies and indifferent will excel. He also says that if a person exhibits the same character towards those whom you dont know and those who hate and whose who are relatives and those who do right things in life as well as the wrong things in life are the ones who excel.
Extending Interpretation to Mankind’s Life!
This sloka talks about the balance that a person has to show in life in treating people who hold different equations and different relationships. Is it easy to treat the same way the way the good hearted person and a friend? The answer is No. We all like a good hearted person because he has a good heart. But we like a friend because he is our friend even if he doesn’t have a good heart. Many times we blindly support the wrong doing of people also just because they are our friends. So brining similarity in treating a good hearted person and a friend is very difficult and only a evolved person can do it.
Like this it is also difficult to treat the enemy and a person who is indifferent equally. We know that enemy is the one whom we have a fight with or whom we dont like. Indifferent person is someone who doesnt respond to us. He is someone who doesnt show interest in you and he stays away from you. Can you treat an enemy and an indifferent person in the same way? The answer here is again No. We harm our enemies and wants to defeat them and we stay from indifferent people and dont keep any relationship with them. Integrate now the friend and a good hearted person and indifferent person and an enemy. A spiritually evolved person treats all of them equally.
