Everything, from the earth it has come up: "Dust thou were, dust thou beist." This beautiful body, nice body, will become earth. And those who are burning, so their body becomes ashes. And those who throw the body to be eaten by jackals and crows, they become stool. This is the end of the body. We are taking so much care of this body, but the ultimate end of this body is either stool, earth or ashes. So foolish persons who are in the bodily concept of life, they are thinking: "After all, this body will be finished. So so long the body is there, senses are there, let us enjoy. Why so much restrictions, no illicit sex, no gambling? No. These are all nonsense. Let us enjoy life." This is atheistic life. Foolish life. They do not know, so the body is not all.
This is the first lesson to understand, what is spiritual life, what is spiritual knowledge. But all rascals, they do not know. Therefore Kṛṣṇa first of all slapped Arjuna: aśocyān anvaśocas tvaṁ prajñā-vādāṁś ca bhāṣase (BG 2.11). "You do not know what is the fact, and talking like a very learned man. Just try to understand what is truth." Na tv evāhaṁ jātu nāsam. First thing is that nāsam, we have no nāsam. We never die, that will be explained later on more clearly, we do not die. Nāsam. At any time. It is not that sometimes we die and sometimes... No. Any time, jātu. At any time. So: "Sir, You are Supreme Personality of Godhead, You may not die. But we die, we are ordinary living entities."
