The material existence means we are servant of so many sense gratificatory processes. Nūnaṁ pramattaḥ kurute vikarma (SB 5.5.4). We are now engaged to act sinfully. Any kind of sinful activity we can accept. Why? Yad indriya prītaya āpṛnoti. Simply for sense gratification. That's all. We are prepared to take any risk only for sense gratification. But we do not know that we are taking great risk, great risk. Because there is another life. After death, there is life. The modern people, they do not understand it. Therefore śāstra says, na sādhu manye: "These kinds of activities are not very good." Na sādhu. It is not honest. This is not good.
