It is not infrequent for a person overly attached to the material body to request a physician to prolong his life at least for some time. If the so-called scientific physician is able to prolong ones life for a few minutes through the use of oxygen or other medicines, he thinks that he is very successful in his attempts, although ultimately the patient will die. This is called the struggle for existence. At the time of death both patient and physician still think of prolonging life, although all the constituents of the body are practically dead and gone.
