Srila Prabhupada - Vedic Teachings

  „He supplies everything to everyone. He is supplying food to everyone. So He is the Father. So why should you not pray, "Father, give me this"? Just as in the Christian Bible there is, "Father, give us our daily bread." That is good-they are accepting the Supreme Father. But grown-up children should not ask from the father; rather, they should be prepared to serve the father. That is bhakti [devotion].” (Perfect Questions, Perfect Answers -The Real Goal of Life)  

  "If one thinks he is big devotee that is not good, thinking that he is first degree. We should not be puffed up, a devotee avoids it, remaining always in the second degree. A dog is a faithful servant. To become lowest dog is to become on the highest platform of service. Krsna has given everyone something extraordinary and to serve Krsna with one's extraordinary talent means successful life." (Srila Prabhupada’s letter to: Sukadeva—Calcutta 73-03-04)
