Every conditioned soul, as we are, we have got four defects, namely we commit mistake, we are sometimes illusioned, and sometimes we do not know properly anything, and still, I give my thesis, "Perhaps, it may be..." What is this knowledge "perhaps"? That means cheating. One hasn't sufficient knowledge and "perhaps, maybe"—he is giving knowledge. And above all of them, we should know that our present material senses are imperfect. For example, just like we are very much proud of our eyes. We say, "Can you show me God?" But our eyes are so long perfect as long the light is. It is conditional. Therefore every sense now we are possessing, they are not perfect. So we acquire knowledge by using our different senses. Therefore, because they are imperfect, whatever knowledge we gather by speculation, that is imperfect.
So if we take knowledge from such personalities who are liberated, then that knowledge is perfect. This is the process of acquiring knowledge in Kṛṣṇa consciousness movement—that we receive knowledge from the perfect person. Now, here it is said that because it is given by the perfect person Vyāsadeva, we should take knowledge from this Śrīmad-Bhāgavatam. And the proof is that we have now become Godless, we have no information of God, but if you read Śrīmad-Bhāgavatam, then immediately you will realize God. Just like you can see in reality that these boys, these girls who have joined this Kṛṣṇa consciousness movement, because they are reading Śrīmad-Bhāgavatam, Bhagavad-gītā, they are now gradually realizing what is God and what is his relationship with God. So unless we realize God and our position, and we become lover of God, there is no question of peace in the mind. Therefore it is recommended here that if you want real peace in the mind, try to understand what is God, what is your relationship with God, and act accordingly. You will be immediately peaceful. As soon as you become peaceful, your life is successful. Thank you very much.
