There are many big cities all over the surface of the globe, and wherever one looks he sees the struggle for existence going on twenty-four hours a day. people rush about in cars going seventy and eighty miles an hour, constantly coming and going, and this sets the scene of the great struggle for existence. One has to rise early in the morning and travel in that car at breakneck speed. There is always the danger of an accident, and one has to take great care. In his automobile, the living entity is full of anxieties, and his struggle is not at all auspicious. Apart from human beings, other species like cats and dogs are also struggling very hard day and night for existence. Thus the struggle for existence continues, and the conditioned soul changes from one position to another. (SB 5.14.1)
As long as we have these bodies this struggle must go on. If we only work for the body and the things relating to the body we simply will be fighting a battle that we are destined to lose against death.
On the other hand, if we spend whatever time we have reading Srila Prabhupada’s books and chanting Hare Krishna Hare Krishna Krishna Krishna Hare Hare Hare Rama Hare Rama Rama Rama Hare Hare, then that will make us happy, fulfilled and ultimately in the end when these bodies do lose the battle to death everything will not be lost. Because all the transcendental activities we did will stick with us and liberate us from the repetition of birth and death, samsara, and we will return back home back to Krishna, that is the happy ending!
