A father wanted to test the intelligence of his two sons. He allotted to each of them the task of looking after a mango tree, promising to reward the boy whose tree yielded the best fruit in abundance. The foolish boy discovered that the leaves were withering off and that flowers were coming up at the end of the branches. Promptly he went up the tree and carefully watered every leaf. The leaves withered still more and the tree eventually died. The wise boy, on the other hand, went on watering the root; the tree was green and healthy and yielded delicious fruits in abundance.
Similarly, God gives human birth to man in order to test the evolution of his intelligence. The foolish man, eager to get the reward of Eternal Peace and Immortality, seeks to pay attention to the satisfaction of his sense-cravings, and to the acquisition of worldly knowledge, for he thinks that it is the right way. He dies the miserable death of an ignorant man. The wise man, on the
contrary, devotes himself to the contemplation of God, the Root of all Creation, and thus obtains all the wealth and knowledge of the universe. God is well pleased with him and bestows upon him the reward of Immortality and Eternal Bliss.
