Bhagavad Gita Verse 19, Chapter 12

tulyanindaastutirmauni santushto yena kenachita |
aniketaha sthiramatirbhaktimaanme priyo naraha || 19 ||
 
To whom praise and insult are same, who is silent, content with anything, who is without a home, with unwavering mind, a person who is such a devotee is dear to me.
 
tulyanindaastutihi : praise and insult are same
mauni : one who is silent
santushtaha : content
yena kenachita : with anything
aniketaha : without a home
sthiramatihi : unwavering mind
bhaktimaan : devotee
me : me
priyaha : dear
naraha : person
 
Shri Krishna continues summarizing the twelfth chapter in this shloka by listing further attributes of the perfected devotee. He first says that both praise and insult have no effect on the devotee. Praise and insult are usually targeted towards a person's name. But the devotee, having given up all identification with his name, does not care whether he is praised or insulted, just like the sky does not get affected whether someone throws roses at it or dirt. The devotee is also a mauni, one who remains silent. Here, the silence does not refer to verbal silence but to silence of desires and thoughts that are devoid of Ishvara as their basis.
 
The ocean is not affected whether it gets a torrential downpour or no rain at all. It happily accepts whatever comes its way because it is content with itself. Similarly, the devotee is content in his constant devotion to Ishvara, and therefore accepts whatever comes his way without any complaint. The devotee also does not have an attitude of possession towards anything, including his home. Like the wind that comes and goes anywhere as it pleases, the devotee considers the entire world his home and is attached his house, his physical body, his mind, his intellect or his desires.
 
As we proceed along the path of devotion, we will notice that our mind shifts between giving reality to the world as part of Ishvara, and giving reality to the world as separate from Ishvara. As long as we give reality to the world as an independent entity, we can never get rid of our unfulfilled desires, and the attachment to the world that results from those desires. A perfected devotee is one whose mind is fixed on giving reality to the world as a part of Ishvara, giving up all selfish desires in the process. Shri Krishna says that a person who harbours all these attributes is fit to be called a naraha, a human being, in the true sense of the world. Such a devoted person is very dear to him.

In the previous shloka, Shri Krishna described the attitude of a perfected devotee towards the performance of actions. He now elaborates upon the attitude of a perfected devotee towards situations, objects, thoughts and emotions that he encounters. These may come to him either as a result of his actions or as a matter of course in his daily life.
 
When we usually encounter a situation or obtain an object, we are either attracted to it, repulsed by it or are indifferent to it. Attraction generates desires that are stored in our mind, and repulsion generates negative desires, a list of things we would like to stay away from. If we eventually get the favourable object, or hold on to the favourable situation long enough, we become "harshita", we rejoice. But if we lose that object or situation, which is bound to happen sometime, we become "shochita", we grieve. Attraction, revulsion, desire, hatred, joy, grief - this is how most of us usually operate.
 
The perfected devotee, however, has tackled this problem at its root. He has stopped labelling any object, person, situation or thought as either good or bad, because it is exactly this labelling that starts the chain reaction of attraction, desire, joy and sorrow. He is like the model student who does not label his teacher's feedback as good or bad, whether it be praise or criticism, because he has the utmost faith in his teacher. The perfected devotee accepts all objects and situations as Ishvara's blessings, does what he has to do, and moves on. Shri Krishna says that one who accepts whatever comes with way due to his faith and devotion to Ishvara, is dear to him.
