अद्वेष्टा सर्वभूतानां मैत्रः करुण एव च। निर्ममो निरहङ्कारः समदुःखसुखः क्षमी ॥

adveṣhṭā sarva-bhūtānāṁ maitraḥ karuṇa eva cha nirmamo nirahankāraḥ sama-duḥkha-sukhaḥ kṣhamī

He who beareth no ill-will to any being, friendly and compassionate, without attachment and egoism, balanced in pleasure and pain, and forgiving,

In plain words: Krishna begins to describe the kind of person he loves. This person holds no grudge against anyone and is friendly and kind. They are not clingy or self-centered, they stay steady in good times and bad, and they forgive.
