Section 19: Choose The Larger Fields Of Wisdom explained simply

XIX. Betake yourself to these quieter, safer, larger fields of action: do you think that there can be any comparison between seeing that corn is deposited in the public granary without being stolen by the fraud or spoilt by the carelessness of the importer, that it does not suffer from damp or overheating, and that it measures and weighs as much as it ought, and beginning the study of sacred and divine knowledge, which will teach you of what elements the gods are formed, what are their pleasures, their position, their form? to what changes your soul has to look forward? where Nature will place us when we are dismissed from our bodies? what that principle is which holds all the heaviest particles of our universe in the middle, suspends the lighter ones above, puts fire highest of all, and causes the stars to rise in their courses, with many other matters, full of marvels? Will you not cease to grovel on earth and turn your mind’s eye on these themes? nay, while your blood still flows swiftly, before your knees grow feeble, you ought to take the better path. In this course of life there await you many good things, such as love and practice of the virtues, forgetfulness of passions, knowledge of how to live and die, deep repose. The position of all busy men is unhappy, but most unhappy of all is that of those who do not even labour at their own affairs, but have to regulate their rest by another man’s sleep, their walk by another man’s pace, and whose very love and hate, the freest things in the world, are at another’s bidding. If such men wish to know how short their lives are, let them think how small a fraction of them is their own.
