Prabhupada's lecture - Śrīmad-Bhāgavatam 1.15.24 - Los Angeles, December 3, 1973
Now we have to learn that we have been frustrated by serving so many things. Now we have to turn that service attitude to Kṛṣṇa. That is Kṛṣṇa's mission. Sarva-dharmān parityajya mām ekaṁ śaraṇaṁ vraja: [Bg. 18.66] "You are serving already. You cannot be free from service. But your service is misplaced. Therefore you just turn your service unto Me. Then you become happy." That is Kṛṣṇa consciousness movement. Kāmādīnāṁ kati na katidhā pālitā durnideśāḥ. Because we are greedy... Just like a greedy man, he is suffering by eating more. There are so many diseases, just like diabetes or dysentery. There are so many things. These are the diseases for eating more. That's all. So we are suffering; at the same time, we are eating more. Because we are greedy, we are lusty. This is the cause. So therefore kāmād... We are serving. We are serving our lust, our greediness, and suffering.
This is practical. If you have no hunger, if you eat... If you have no appetite, if you eat, then you suffer. If you infect some disease, you'll suffer. That is practical. So we are associating in, being infected by lust, greediness, illusion, fearfulness, so many things. Sadā samudvigna-dhiyam asad-grahat [SB 7.5.5]. If you steal, then you will be under fearfulness: "Oh, I may not be arrested; I may be arrested." Because you have done that, asad-grahat, you have done something wrong, therefore you are under the influence of fearfulness. It is very easy to understand.
