Kṛṣṇa is not hankering after your decoration, after your nice foodstuff, because He is full perfect, ātmārāma. He can create any kind of comforts, He is so powerful. But He is so kind that He comes to you in a form which you can handle to serve Him: this arcā-mūrti. Kṛṣṇa is so kind. Because you cannot see at the present moment Kṛṣṇa in spiritual identity, therefore Kṛṣṇa comes before you as stone, as wood. But He is not stone; He is not wood.
The same example I have given several times, that the post office gives you a letterbox in front of your house. But that little box is not a letter . . . an ordinary box; it is post office. It is post office actually. If you imitate a box like that, and if you put your letter, that will not go. But in that authorized box if you put your letters, it will go any part of the world. So that box, do not consider that it is ordinary box. It is the whole post office, whole postal department. But for your convenience the postal department has come before you like a small box.
