If you think of Kṛṣṇa within yourself, that "Kṛṣṇa is like this, Kṛṣṇa's leg is like this, Kṛṣṇa's flute is like this, Kṛṣṇa's hand is like this, mouth is like this, He is dressed like this," this meditation is perfect meditation—not imagination—so that your mind will be gradually absorbed in Kṛṣṇa.
So Kṛṣṇa comes, therefore, personally and exhibits this Kṛṣṇa mūrti. Just like here is the picture of your spiritual master. So you worship this picture. You know that, "This is my spiritual master's picture." Similarly, if somebody disregards this picture, you will not tolerate. Similarly, Kṛṣṇa's Deity and Kṛṣṇa not different. I was explaining this morning, Kṛṣṇa has come, kindly, to accept your service as you can deal with Him. If Kṛṣṇa comes in His gigantic form—Kṛṣṇa has got gigantic form also, as it was shown to Arjuna—you will not be able to capture Him, neither you have any means to dress Him. Suppose the universal form of Kṛṣṇa is there, and you have to dress Him, (laughter) so the whole cloth factory will be finished. (laughter) Is it not? How you can dress? You have no capacity to dress. But Kṛṣṇa has kindly accepted a form, the Deity. You can purchase cloth according to your means, and with your great devotion, you can dress. Similarly, the gigantic virāṭ-rūpa, universal form, the whole, it is described in the Bhagavad-gītā that He is eating, the whole humanity is going on in His mouth. Then where you will get such food? (laughter) The whole humanity, the whole universal living entities can be devoured by Kṛṣṇa. But because you are not able to offer such gigantic food to Kṛṣṇa, Kṛṣṇa says: "All right, give Me patraṁ puṣpaṁ phalaṁ toyam. Give Me a little flower, give Me a little fruit, give Me a little water, I shall accept it." This is called arcana-viddhi. Kṛṣṇa has agreed to accept your service as you can afford to do. It is not idol worship. It is actually worshiping Kṛṣṇa.
