"Serving means with love. Now just like these boys, my disciples, they are serving me. Whatever I say, they are immediately executing. Why? I am an Indian, I am a foreigner. Two or three years ago I was not known to them, nor they were known to me. Why they are doing that? Because it is love. Serving means developing love. So unless you develop your love for God you cannot serve Him. Anywhere. Whenever you give some service, it is based on love. Just like mother giving service to the helpless child. Why? Love. So similarly, our life will be perfect when our love is perfect with the perfect Supreme Personality of Godhead. Then it is all right. You have to learn this. This is Kṛṣṇa consciousness: in a relationship with Kṛṣṇa. Just like I am loving my disciples, my disciples are loving me. Why? What is the medium? Kṛṣṇa."
