Answer: In our world, in order to get the fruits of plants, it is necessary to grow a tree for a long time, to perform certain manipulations on it, to care for, to fertilize it, to water it, and so on. And when we reach the full ripening of the fruit, then we can use it.
In the spiritual world, the fruit means real knowledge. Spiritual knowledge is knowledge about everything that surrounds us, about external and internal forces, and most importantly, about their source—the Creator.
