Nothing important comes into being overnight; even grapes or figs need time to ripen. If you say that you want a fig now, I will tell you to be patient. First, you must allow the tree to flower, then put forth fruit; then you have to wait until the fruit is ripe. So if the fruit of a fig tree is not brought to maturity instantly or in an hour, how do you expect the human mind to come to fruition, so quickly and easily?
