It is important to master the mind by fixing it on the Supreme Lord, to prevent it from going astray in various ways. The mind will then be said to be established at the level of pure knowledge, where the devotee understands that Krishna is the fundamental principle of all that we are aware of. After many lifetimes devoted to cultivating knowledge, a person relies on Vasudeva (full emanation of Krishna), realizing that Krishna is present in all things and He is entering the entire cosmic manifestation. Although under the control of the Supreme Lord and located in his energy, everything is nonetheless different from Krishna in his personal form. Fixing your mind on Krishna is emotional.

The Supreme Lord himself said: Unless one ascends to the level of mastery of the senses, one cannot know all the greatness of Krishna, nor the diffusion of his various energies, the causes of all manifestations.

Mental equilibrium can be acquired by who comes to the conclusion that God, the Supreme Person, is the primary source of all things. As for tolerance, it is the attitude of a person ready to tolerate all kinds of tribulations in order to acquire mastery of the senses and mental balance. Also called dhriti, the ability to resist impulses from the tongue and genitals. A person thus appeased becomes what is called a dhira.

When one succeeds in fixing one's mind unswervingly on Krishna, one succeeds in establishing oneself steadily in Krishna consciousness. It is the neutral, calm, peaceful, gentle relationship, in which an unshakeable faith in Krishna settles and in which all material desires, that is, unrelated to Krishna, end. This double characteristic of the neutral relationship is also found in other feelings, in the same way that sound is generally present in all other elements, air, fire, water and earth, since it emanates from the ether. All spiritual relationships, whether under the sign of service, brotherhood, parental affection or marital love, thus possess this double characteristic of the neutral relationship, an unshakeable faith in Krishna and the absence of desire for all that is not Krishna. When we say what is not Krishna, we should not conclude that there can be anything besides Him. On the contrary, since everything is produced from the energy of Krishna. As Krishna and his energies turn out to be the same, everything is indirectly Krishna. For example, consciousness is characteristic of all living beings. But when the consciousness is totally focused on Krishna, what is called Krishna consciousness, it is said to be pure. When it is focused on the pleasures of the senses and not on Krishna, it can be called Krishna unconsciousness. It is from this impure condition that the concept of the absence of Krishna arises. In its purest form, however, there is only Krishna consciousness. A clear interest in Krishna, that Krishna is mine, or vice versa, and my purpose is to serve his senses, falls on a higher level than neutral love. It suffices to grasp the greatness of Krishna to access the neutral relationship, where the object of worship is the Supreme Impersonal Being or the Supreme Soul. It is this form of worship favored by the followers of empirical speculation and the yoga of powers. Anyone who further develops their Krishna consciousness, their spiritual understanding, will realize that the Supreme Soul embodies the eternal object of worship and surrender to Him.
