"They pick up riches as bees roaming round pick up pollen. And their riches proceed to grow, like an ant-hill piling up. In gathering wealth like this, a householder does enough for their family. And they’d hold on to friends by dividing their wealth in four. One portion is to enjoy. Two parts invest in work. And the fourth should be kept for times of trouble."
