Birth leads to death, death precedes birth. So if you want to see life as it really is, it is rounded on both the sides by death. Death is the beginning and death is again the end, and life is just the illusion in between. You feel alive between two deaths; the passage joining one death to another you call life. Buddha says this is not life. This life is dukkha - misery. This life is death.
It is good to love God for hope of reward, but it is better to love God for love's sake; and the prayer goes: O Lord, I do not want wealth nor children nor learning. If it be Thy will, I shall go from birth to birth. But grant me this, that I may love thee without the hope of reward 'love' unselfishly for love's sake.
All men, and all created nature, have been at work, from the beginning of time to this day, to produce the circumstances which now influence our actions. AS soon as an act has been performed, it becomes independent of the individual performing it, and forthwith gives birth to some other act, which last gives birth to still another, and so they continue, and will continue, until the law of cause and effect shall cease to operate.
