That means the birds have eaten them, and they have thrown so many. So God supplies immense bread or eatable things without any asking. In a African jungle there are hundreds, thousands of elephants. They eat, at a time, huge quantity of food. But still, they are supplied by God. Actually, even from practical point of view—I have traveled all over the world—there are immense place. We can produce foodstuff for supplying food, ten times of the whole world population. So therefore there is no need of approaching God with a motive for material supplies or material satisfaction.
In the Vedic literature we get information, nityo nityānāṁ cetanaś cetanānām, eko yo bahūnāṁ vidadhāti kāmān (Kaṭha Upaniṣad 2.2.13). God, the description of God, is given there that "He is also living entity like us. He is also eternal like us." Nityo nityānāṁ cetanaś cetanānām. But what is the difference between Him and us? That is described, eko yo bahūnāṁ vidadhāti kāmān: "That one God is supplying all the necessities of these many." So we should not approach God for economic satisfaction or for bread or for wood or for anything necessary for our life. God has arranged food for everyone, the aquatics, the birds, the beasts, the trees, the elephants or the other, four-legged animals, and why not for human being? Human being also, those who are uncivilized, still living in the forest, they have no arrangement for economic development, or they do not know, but they have got also food.
