So if everyone says that "Original cause of my existence is Kṛṣṇa," this is Kṛṣṇa consciousness. It doesn't matter. Not that a brāhmaṇa... Brāhmaṇa is the mouth of Kṛṣṇa, and kṣatriya is the arm of Kṛṣṇa, and vaiśya is the belly of Kṛṣṇa, and śūdra is the leg of Kṛṣṇa. But do we distinguish that "Here is Kṛṣṇa's mouth, or head; all the flowers should be offered here, not to the leg"? Do we make any such distinction? When we worship Kṛṣṇa, rather, our first duty is to offer to the lotus feet of Kṛṣṇa. And Kṛṣṇa says that śūdra, in Bhāgavata says, śūdra is the leg. So there may be distinction of profession, occupation, caste, creed, color... It doesn't matter. But if everyone tries to become Kṛṣṇa conscious, that "The original cause of my existence is Kṛṣṇa," then there is life... Life is perfect. This is our Kṛṣṇa consciousness movement. Not blindly, but by research work, that how the original cause is Kṛṣṇa? Kṛṣṇa says, ahaṁ sarvasya prabhavo mattaḥ sarvaṁ pravartate (BG 10.8): "I am the original cause of everything. Everything emanates from Me." How can I deny that Kṛṣṇa is not cause? This is Kṛṣṇa consciousness. Therefore, those who are advanced devotee, he does not see anything else but Kṛṣṇa. Because Kṛṣṇa is the cause of everything. That is required. Therefore he's Kṛṣṇa consciousness.
According to the Vedic injunctions, a brahmana is the mouth of the Supreme Personality of Godhead; therefore in all rituals a brahmana is offered food because when a brahmana eats, it is considered that the Supreme Lord Himself eats
SB Canto 5
The Supreme Personality of Godhead replied: O great sages, I am certainly very pleased with your prayers. You are all truthful. You have prayed for the benediction of a son like Me for King Nābhi, but this is very difficult to obtain. Since I am the Supreme Person without a second and since no one is equal to Me, another personality like Me is not possible to find. In any case, because you are all qualified brāhmaṇas, your vibrations should not prove untrue. I consider the brāhmaṇas who are well qualified with brahminical qualities to be as good as My own mouth.
The word avitatha-gīrbhiḥ means "they whose spoken vibrations cannot be nullified." The brāhmaṇas (dvija, the twice-born), are given a chance by the śāstric regulations to become almost as powerful as the Supreme Lord. Whatever a brāhmaṇa speaks cannot be nullified or changed in any circumstance. According to the Vedic injunctions, a brāhmaṇa is the mouth of the Supreme Personality of Godhead; therefore in all rituals a brāhmaṇa is offered food (brāhmaṇa-bhojana) because when a brāhmaṇa eats, it is considered that the Supreme Lord Himself eats. Similarly, whatever a brāhmaṇa speaks cannot be changed. It must act. The learned sages who were priests at Mahārāja Nābhi's sacrifice were not only brāhmaṇas but were so qualified that they were like devas, demigods, or God Himself. If this were not the case, how could they invite Lord Viṣṇu to come to the sacrificial arena? God is one, and God does not belong to this or that religion. In Kali-yuga, different religious sects consider their God to be different from the God of others, but that is not possible. God is one, and He is appreciated according to different angles of vision. In this verse the word kaivalyāt means that God has no competitor. There is only one God. In the Śvetāśvatara Upaniṣad (6.8) it is said, na tat-samaś cābhyadhikaś ca dṛśyate: "No one is found to be equal to Him or greater than Him." That is the definition of God.
In the Śrīmad-Bhāgavatam the definition of mukti has been given that muktir hitvā anyathā rūpam. Anyathā rūpam. I am identifying now myself as this and that. "I am American; I am Indian; I am brāhmaṇa; I am gosvāmī; I am this, that..." No. This is all anarthas, unwanted. So therefore hitvā anyathā rūpam. We are living under the impression of something else. Hitvā means when we give up this wrong impression. And sva-rūpeṇa vyavasthitiḥ, when you are situated in your original position, that is called mukti. Mukti does not mean anything else. This is the definition of mukti.
You keep yourself in your original position. So our original position is part and parcel of Kṛṣṇa. We are part and parcel of the body of Kṛṣṇa. The brāhmaṇa is the mouth of Kṛṣṇa, and the kṣatriyas are the arms of Kṛṣṇa. The vaiśyas are the abdomen of Kṛṣṇa, and the śūdras are the legs of Kṛṣṇa. Mukha-bāhūru-pādebhyaḥ jajñire catvāro varṇā viprādayo guṇair pṛthak. The... Nobody should be hated. Just like in your body your leg is as important as your head, especially of Kṛṣṇa. Kṛṣṇa is advaya-jñāna, absolute. We may make some difference from head to leg. Leg is less important, head is... No. But Kṛṣṇa's any part is as important as other part. So you become the part of... You are already. But if you come to realize that you are part and parcel of Kṛṣṇa, Kṛṣṇa's body, so either you act as Kṛṣṇa's leg or as Kṛṣṇa's head, there is no difference. There is no difference.
