No man can live happily who regards himself alone, who turns everything to his own advantage. Thou must live for another, if thou wishest to live for thyself.
Seneca the YoungerEveryone rushes his life on, and suffers from a yearning for the future and a boredom with the present. But that man who devotes every hour to his own needs, who plans every day as if it were his last, neither longs for nor fears tomorrow.
Seneca the YoungerThere are many things akin to highest deity that are still obscure. Some may be too subtle for our powers of comprehension, others imperceptible to us because such exalted majesty conceals itself in the holiest part of its sanctuary, forbidding access to any power save that of the spirit. How many heavenly bodies revolve unseen by human eye!
