One can curb the forces of sense gratification only by means of Krishna consciousness, or engaging all the senses in the transcendental loving service of the Lord. As enemies are curbed by superior force, the senses can similarly be curbed, not by any human endeavor, but only by keeping them engaged in the service of the Lord. One who has understood this — that only by Krishna consciousness is one really established in intelligence and that one should practice this art under the guidance of a bona fide spiritual master — is called sadhaka, or a suitable candidate for liberation.
11.12, 5.7, 7.23
One who is on the path of liberation by Krishna consciousness is very dear to every living being, and every living being is dear to him. This is due to his Krishna consciousness. Such a person cannot think of any living being as separate from Krishna, just as the leaves and branches of a tree are not separate from the tree. He knows very well that by pouring water on the root of the tree, the water will be distributed to all the leaves and branches, or by supplying food to the stomach, the energy is automatically distributed throughout the body. Because one who works in Krishna consciousness is servant to all, he is very dear to everyone. And because everyone is satisfied by his work, he is pure in consciousness. Because he is pure in consciousness, his mind is completely controlled. And because his mind is controlled, his senses are also controlled. Because his mind is always fixed on Krishna, there is no chance of his being deviated from Krishna. Nor is there a chance that he will engage his senses in matters other than the service of the Lord. He does not like to hear anything except topics relating to Krishna; he does not like to eat anything which is not offered to Krishna; and he does not wish to go anywhere if Krishna is not involved. Therefore, his senses are controlled. A man of controlled senses cannot be offensive to anyone.
Here the point may be raised that if the demigods are different parts of the body of the Supreme Lord, then the same end should be achieved by worshiping them. However, worshipers of the demigods are less intelligent because they don’t know to what part of the body food must be supplied. Some of them are so foolish that they claim that there are many parts and many ways to supply food. This isn’t very sanguine. Can anyone supply food to the body through the ears or eyes? They do not know that these demigods are different parts of the universal body of the Supreme Lord, and in their ignorance they believe that each and every demigod is a separate God and a competitor of the Supreme Lord.
One who is fully conversant with the Krishna science becomes eligible to enter into the spiritual kingdom, the abode of Krishna. Becoming Brahman does not mean that one loses his identity. Devotional service is there, and as long as devotional service exists, there must be God, the devotee, and the process of devotional service. Such knowledge is never vanquished, even after liberation. Liberation involves getting free from the concept of material life; in spiritual life the same distinction is there, the same individuality is there, but in pure Krishna consciousness. One should not mistakenly think that the word visate, “enters into Me,” supports the monist theory that one becomes homogeneous with the impersonal Brahman. No. Visate means that one can enter into the abode of the Supreme Lord in one’s individuality to engage in His association and render service unto Him. For instance, a green bird enters a green tree not to become one with the tree but to enjoy the fruits of the tree. impersonalists generally give the example of a river flowing into the ocean and merging. This may be a source of happiness for the impersonalist, but the personalist keeps his personal individuality like an aquatic in the ocean. We find so many living entities within the ocean, if we go deep. Surface acquaintance with the ocean is not sufficient; one must have complete knowledge of the aquatics living in the ocean depths.
