"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."
(Srila Prabhupada Lecture, Seattle, September 30, 1968)
"A person may have a bona fide spiritual master and may be attached to a spiritual organization, but still, if he is not intelligent enough to make progress, then Kṛṣṇa from within gives him instructions so that he may ultimately come to Him without difficulty. The qualification is that a person always engage himself in Kṛṣṇa consciousness and with love and devotion render all kinds of services. He should perform some sort of work for Kṛṣṇa, and that work should be with love. If a devotee is intelligent enough, he will make progress on the path of self-realization. If one is sincere and devoted to the activities of devotional service, the Lord gives him a chance to make progress and ultimately attain to Him."
(Bhagavad-gītā As It Is 10.10, Purport)
"If there is some discrepancy anywhere, some non-cooperation, fighting, or if the work is slow or not to the standard, it is to be supposed that the person or persons in charge are not very much attached to Krishna. That means they will discriminate: my engagement is not good, other's engagement is good, like that. They do not know the secret of surrendering to Krishna. Such surrendered devotee sees that everything is part of Krishna's plan, that whatever is meant to be, I am doing that, so let me do it with my full attention to every detail, let me become absorbed in such service, never mind what it is, but let all other considerations be forgotten and only my desire to do the thing best for Krishna's alone pleasure be my motive. That is advanced stage of understanding devotional service or Krishna Consciousness."
(Srila Prabhupada Letter, December 19, 1972)
