You know, Lord, that a great multitude cannot exist without much diversity and that almost all are compelled to lead a laborious life full of troubles and afflictions, and in servile subjugation must be subject to the kings who rule. Hence it has occurred, that only a few men have enough leisure time to employ the freedom of their will and to gain knowledge of themselves. They are distracted by many corporeal cares and duties. Thus they cannot seek You, who are the concealed God.
