Bhagavad-Gita: Chapter 12, Verse 15

Rudra Vaisnava Sampradaya:

Visnuswami

Sridhara Swami's Commentary

From whom the world gets no disturbance and to whom is never disturbed by the world, to who is free from mundane pleasure is free from attachment and to who is free from elation is free from desire and to who is free from jealousy is free from envy at another's gain. Fear is terror coming from apprehension from danger. Anxiety is the agitation of the mind because of it. Lord Krishna's devotee who is free from all these things is very dear to Him.

Brahma Vaisnava Sampradaya:

Madhvacarya
There is no commentary for this verse.

Sri Vaisnava Sampradaya:

Ramanuja

Ramanuja's Commentary

That person who by their actions do not become a cause of fear or trouble in their life and causing no affliction to the world has no cause to feel afflicted by the world. As no elements of antagonism exist in such a one, no action received from the world can be taken as being aggression at any time. One who is free from giving or receiving joy and grief to any being who is free from all conceptions of being the bestower of anything or the recipient of anything is very dear to the Supreme Lord Krishna.

Kumara Vaisnava Sampradaya:

Nimbaditya

Kesava Kasmiri's Commentary

One who is not an annoyance or disturbance to anyone or anything and who also does not feel any annoyance or disturbance from anybody or anything, being antagonistic to no one is equal to all and thus freed from the mental fluctuations of elation, intolerance, fear and anxiety is very dear to the Supreme Lord Krishna.
