As the embodied soul continually passes, in this body, from boyhood to youth to old age, the soul similarly passes into another body at death. The self-realized soul is not bewildered by such a change. (Bg. 2.13) Unfortunately, this spiritual education is completely absent from modern human civilization. No one understands his real self-interest, which lies with the spirit soul, not with the material body. Education means spiritual education. To work hard in the bodily conception of life, without spiritual education, is to live like an animal. Nayam deho deha-bhajam nr-loke kastan kaman arhate vid-bhujam ye (Bhag. 5.5.1). People are working so hard simply for bodily comforts, without education regarding the spirit soul. Thus they are living in a very risky civilization, for it is a fact that the spirit soul has to transmigrate from one body to another (tatha dehantara-praptih). Without spiritual education, people are kept in dark ignorance and do not know what will happen to them after the annihilation of the present body. They are working blindly, and blind leaders are directing them. Andha yathandhair upaniyamanas te pisa-tantryam uru-damni baddhah (Bhag. 7.5.31). A foolish person does not know that he is completely under the bondage of material nature and that after death material nature will impose upon him a certain type of body, which he will have to accept. He does not know that although in his present body he may be a very important man, he may next get the body of an animal or tree because of his ignorant activities in the modes of material nature. Therefore the Krsna consciousness movement is trying to give the true light of spiritual existence to all living entities. This movement is not very difficult to understand, and people must take advantage of it, for it will save them from the risky life of irresponsibility.
