We are passing through many phases of life, different dresses. Vāsāṁsi. Bhagavad-gītā says, vāsāṁsi jīrṇāni yathā vihāya (BG 2.22).
Just like I am putting on this dress. If it is dirty or if it is very old, then I change; I accept another dress. Similarly, this body is also like that. When it is dirty or when it is old enough, not to be used, then we change to another body, and this body we leave. This is the whole instruction of all Vedic literature.
Therefore the activities of this body is not all. And as there are different types of body, as we have come to this body, this status of body, passing through many, many types of abominable body—aquatics, beasts, trees, plants, microbes, reptiles, so many . . . repeatedly we have said, 8,400,000's of . . . so this is an opportunity. This life, this human form of life, is an opportunity to make further progress. It is not that after this human body is finished, then there is no life.
This misconception, this misleading philosophy, that after death there is nothing, void, is killing the human civilization. Is killing practically. They do not know, "What is my next life?" The next life is there. As there are . . . you can see so many varieties of planets, so there are lives also, different grades of lives, different standard of life. Take for example the moon planet. What do they know about moon? They are trying to reach there by some mechanical means. That is not possible. Anyway, even if it is possible, one should know what is the standard of life there. That you can get from Vedic literature.
