Ages and the Phoenix

For ages there have been decadence,
the denudation of the life's essence;
life is but a fight of the presence,
ages have built the castles of dreams in air,
people let go of them in acute despair;
of spirits people are in arrears,
fortitude and bonanza allay their fears;
since the dawn of civilization there have been mind's insurgence,
which is nothing but the Phoenix's resurgence
