So nobody is immortal within this material world. And still, we are attached. We want to be immortal. That is the psychology. Just like last night, when the snake . . . we do not . . . we did not want to be killed by the snake. We became disturbed. Why this psychology? Because we don't want to be dead, because we are eternal. Na hanyate hanyamāne śarīre (BG 2.20). Neither we wish to take the trouble of being changed of the body. Otherwise, why we became disturbed? We know . . . others may not know that we shall not be killed, even bitten by the snake. Na hanyate hanyamāne śarīre. So why we become disturbed? What is the psychology? The basic principle is that we don't want to be killed. We don't want to change the body even. We have got attraction for the body. Even an animal or insect, living very wretched condition of life, still, if you want to kill it, it will protest. It will protest, "No, no. I don't want to be killed." This is the psychology.
So our real business is how to attain that eternal life. That is real business. Other business, they are not important. Tasyaiva hetoḥ prayateta kovido na labhyate yad bhramatām upary adhaḥ (SB 1.5.18). This is the instruction, that we should try how to become again immortal. We are immortal by nature, but we have been covered by another nature, external nature, bahiraṅga-śakti And because we have been entangled with this material body, we have to die. Otherwise there is no death. Na jāyate na mriyate vā (BG 2.20). The living entity does not take birth, neither it dies. Then why we are taking birth and dying? The . . . this question does not arise to the fools and rascals of this materialist world.
