root that we must nourish

What is the root that we must nourish, to get sweet and tasty fruits in life?

 The root of education fulfills itself in the fruit of virtue. Earning a fat salary is not the chief thing one should expect from education. The goal should be the cultivation of virtues. Education is the root of the tree of life. The affection which the individual develops towards kith and kin, the objects of the world, the ideals and the goals, the fancies and fashions - these form the branches and twigs. The blossoms which the tree produces are the intelligence and its manifestations. These flower blossoms yield the fruit of joy (anandam). The sweetness this fruit confers is character. The essence of character is virtue. It is in virtue that the tree of life justifies itself.
