Whole-hearted sacrifice will lift a character up to heights of heroism that are supremely admirable and make life exemplary, though the failure to take the opportunities for sacrifice may lead to crushing of the spirit entirely. Almost inevitably this brings about disturbance of health as well as deterioration of character. The loss of children by death, particularly when there are but one or two children in a family, as is so frequent in modern times, often brings on a state of mental perturbation in which the health of mind and body, especially of women, may suffer severely. Religion, with its development of the spirit of sacrifice, whenever it is taken seriously, is the best possible sheet anchor in such cases, and the gradual diminution of religious feelings and abandonment of religious practice during the present generation have greatly multiplied the tendency to such severe breakdowns. A distinguished scientist. Professor Whittaker, the Royal Astronomer of Ireland, dwelt on the scientific aspect of sacrifice for high purpose in a way that is illuminating and serves to make our generation understand better the enduring nature of sacrifice in creation and the place that it has in the up-building of what is best in life. "Surrender to the will of God generally means the giving up of some of the delights of the world. Like the {63} coral island built up on the accumulations of its own past life, the perfected kingdom is to be reached only by the sacrifice of countless generations of its own up-builders. But--and this is the greatest of all evidence of the divine life within humanity--in all ages men have left the pleasures of their former life to obey the inward call. The long procession that leads to the distant goal is reunited afresh in every generation: and to-day millions have found the joy of a life centered round the words of the Master, 'Repent', 'Follow Me.'" A distinguished mathematician who is at the same time a very well-known physical scientist declared not long since that the formula for happiness may be expressed as follows: h = g/w In this, h stands for the amount of individual happiness and is equal to what the individual has got, g, divided by w, what he wants. If a man has a great deal but wants ever so much more, his fraction of happiness may be comparatively small. If he has got even a little but does not want much more, his fraction of happiness may approach an integer. If he has got anything in the world and does not want anything more, according to the terms of the formula, he is infinitely happy, for one divided by zero equals infinity (1/0=infinity). What is important for men for their happiness then is not so much to try to increase the numerator by adding to or even multiplying their possessions, but to decrease the denominator by lessening their wants and by decreasing the number of things without which they feel that they cannot be happy. {64}
