This is a verse from Śrīmad-Bhāgavatam, Sixth Canto, First Chapter, verse number six. (SB 6.1.6) In the course of conversation... Not conversation. Mahārāja Parīkṣit was hearing Śrīmad-Bhāgavatam from Śukadeva Gosvāmī. This Śrīmad-Bhāgavatam is the summit of all knowledge. Vidyā bhāgavatāvadhiḥ. Amongst the Vedic scholars, the topmost knowledge means to understand Śrīmad-Bhāgavatam. Everything is there. (aside:) This noise has to be stopped. So in all subject matter—physics, chemistry, astronomy, religion, politics, sociology—everything has been fully described, and above all, the science of God is also described. Therefore it is called Bhāgavatam. Bhāgavatam, the word is derived from bhagavān, bhāgavatam. Bhagavān is the first nominative case from the word bhāgavata, and from bhāgavata-Bhāgavatam. Bhāgavatam means in relationship with God and in relationship with the devotees of God. Śrīmad-Bhāgavatam amalaṁ purāṇam.
So this Kṛṣṇa consciousness movement means we are preaching the cult of Bhāgavatam. It is a scientific method. So there were many discussions, and in the Fifth Canto of Śrīmad-Bhāgavatam there is a chronological description of people suffering due to different kinds of sinful activities. Unfortunately, at the present moment people are unaware. They are kept in darkness. Therefore each and every sinful activity, there is punishment. They do not believe in the next life, but they can see practically in this life that if you violate a little laws of nature, you'll be punished immediately. Immediately punished. Just like I have got some pain in this finger, I scratch some nail, that I should not have done. Immediately there is reaction, I'm suffering. Every... You cannot do anything whimsically. As soon as you do it, there is reaction. Take for example just like salt. Salt is necessary. Unless you put little salt in the foodstuff, you cannot eat it. So salt is necessary, but if you put little more, immediately you cannot eat. It will not, not eatable. Because God has given you salt, the seas and oceans of salt, you cannot make it use more than is necessary. If you think that "There is so much salt, let me eat it," no, you can not do. Any, any action. Just like in this material world, sex life is very pleasing, but if you enjoy more, then you become impotent, the reaction. If you can eat say four ounce, and if you eat five ounce, immediately there is indigestion; two days you will have to starve.
