The Supreme Personality of Godhead, Krishna, is worshipable as a father is worshipable for his son. He is the spiritual master because He originally gave the Vedic instructions to Brahma and presently He is also instructing Bhagavad-gita to Arjuna; therefore He is the original spiritual master, and any bona fide spiritual master at the present moment must be a descendant in the line of disciplic succession stemming from Krishna. Without being a representative of Krishna, one cannot become a teacher or spiritual master of transcendental subject matter
Krishna’s devotees relate to Krishna in various relationships; one might treat Krishna as a son, or one might treat Krishna as a husband, as a friend, or as a master. Krishna and Arjuna are related in friendship. As the father tolerates, or the husband or a master tolerates, so Krishna tolerates
Krishna consciousness is such a transcendentally nice thing that automatically material enjoyment becomes distasteful. It is as if a hungry man had satisfied his hunger by a sufficient quantity of nutritious eatables
Persons who are engaged in the worship of demigods are not very intelligent, although such worship is offered to Me indirectly,” Krishna says. For example, when a man pours water on the leaves and branches of a tree without pouring water on the root, he does so without sufficient knowledge or without observing regulative principles. Similarly, the process of rendering service to different parts of the body is to supply food to the stomach. The demigods are, so to speak, different officers and directors in the government of the Supreme Lord. One has to follow the laws made by the government, not by the officers or directors. Similarly, everyone is to offer his worship to the Supreme Lord only. That will automatically satisfy the different officers and directors of the Lord. The officers and directors are engaged as representatives of the government, and to offer some bribe to the officers and directors is illegal. This is stated here as avidhi-purvakam. In other words, Krishna does not approve the unnecessary worship of the demigods
The individual is the passenger in the car of the material body, and intelligence is the driver. Mind is the driving instrument, and the senses are the horses. The self is thus the enjoyer or sufferer in the association of the mind and senses. So it is understood by great thinkers.” Intelligence is supposed to direct the mind, but the mind is so strong and obstinate that it often overcomes even one’s own intelligence, as an acute infection may surpass the efficacy of medicine. Such a strong mind is supposed to be controlled by the practice of yoga, but such practice is never practical for a worldly person like Arjuna. And what can we say of modern man? The simile used here is appropriate: one cannot capture the blowing wind. And it is even more difficult to capture the turbulent mind. The easiest way to control the mind, as suggested by Lord Caitanya, is chanting “Hare Krishna,” the great mantra for deliverance, in all humility. The method prescribed is sa vai manah krishna-padaravindayoh: one must engage one’s mind fully in Krishna. Only then will there remain no other engagements to agitate the mind.
Out of these five basic subject matters in Bhagavad-gita it is established that the Supreme Godhead, or Krishna, or Brahman, or the supreme controller, or Paramatma — you may use whatever name you like — is the greatest of all. The living beings are in quality like the supreme controller. For instance, the Lord has control over the universal affairs of material nature, as will be explained in the later chapters of Bhagavad-gita. Material nature is not independent. She is acting under the directions of the Supreme Lord. As Lord Krishna says, mayadhyakshena prakritih suyate sa-caracaram: “This material nature is working under My direction.” When we see wonderful things happening in the cosmic nature, we should know that behind this cosmic manifestation there is a controller. Nothing could be manifested without being controlled. It is childish not to consider the controller. For instance, a child may think that an automobile is quite wonderful to be able to run without a horse or other animal pulling it, but a sane man knows the nature of the automobile’s engineering arrangement. He always knows that behind the machinery there is a man, a driver. Similarly, the Supreme Lord is the driver under whose direction everything is working. Now the jivas, or the living entities, have been accepted by the Lord, as we will note in the later chapters, as His parts and parcels. A particle of gold is also gold, a drop of water from the ocean is also salty, and similarly we the living entities, being part and parcel of the supreme controller, isvara, or Bhagavan, Lord Sri Krishna, have all the qualities of the Supreme Lord in minute quantity because we are minute isvaras, subordinate isvaras. We are trying to control nature, as presently we are trying to control space or planets, and this tendency to control is there because it is in Krishna. But although we have a tendency to lord it over material nature, we should know that we are not the supreme controller. This is explained in Bhagavad-gita
Arjuna was not the supreme knower, and his decision to fight or not to fight was confined to his limited discretion. Lord Krishna instructed that the individual is not all in all. The Supreme Personality of Godhead, or He Himself, Krishna, as the localized Supersoul, sits in the heart directing the living being. After changing bodies, the living entity forgets his past deeds, but the Supersoul, as the knower of the past, present and future, remains the witness of all his activities. Therefore all the activities of living entities are directed by this Supersoul. The living entity gets what he deserves and is carried by the material body, which is created in the material energy under the direction of the Supersoul. As soon as a living entity is placed in a particular type of body, he has to work under the spell of that bodily situation. A person seated in a high-speed motorcar goes faster than one seated in a slower car, though the living entities, the drivers, may be the same. Similarly, by the order of the Supreme Soul, material nature fashions a particular type of body to a particular type of living entity so that he may work according to his past desires. The living entity is not independent. One should not think himself independent of the Supreme Personality of Godhead. The individual is always under the Lord’s control. Therefore one’s duty is to surrender, and that is the injunction of the next verse.
The Lord tells Arjuna that basically there is no possibility of understanding the Supreme Truth, the Absolute Truth, the Supreme Personality of Godhead, simply by speculating, for the Supreme Truth is so great that it is not possible to understand Him or to achieve Him simply by making a mental effort. Man can go on speculating for several millions of years, and if he is not devoted, if he is not a lover of the Supreme Truth, he will never understand Krishna, or the Supreme Truth. Only by devotional service is the Supreme Truth, Krishna, pleased, and by His inconceivable energy He can reveal Himself to the heart of the pure devotee. The pure devotee always has Krishna within his heart; and with the presence of Krishna, who is just like the sun, the darkness of ignorance is at once dissipated. This is the special mercy rendered to the pure devotee by Krishna
How activities in Krishna consciousness can lead one ultimately to the spiritual goal is described here. There are various activities in Krishna consciousness, and all of them will be described in the following verses. But, for the present, just the principle of Krishna consciousness is described. A conditioned soul, entangled in material contamination, is sure to act in the material atmosphere, and yet he has to get out of such an environment. The process by which the conditioned soul can get out of the material atmosphere is Krishna consciousness. For example, a patient who is suffering from a disorder of the bowels due to overindulgence in milk products is cured by another milk product, namely curds. The materially absorbed conditioned soul can be cured by Krishna consciousness as set forth here in the Gita. This process is generally known as yajna, or activities (sacrifices) simply meant for the satisfaction of Vishnu, or Krishna.
This Gitopanishad, Bhagavad-gita, the essence of all the Upanishads, is just like a cow, and Lord Krishna, who is famous as a cowherd boy, is milking this cow. Arjuna is just like a calf, and learned scholars and pure devotees are to drink the nectarean milk of Bhagavad-gita
Certainly the transcendental body of Sri Krishna is not perishable. He is just like the sun, and maya is like a cloud. In the material world we can see that there is the sun and that there are clouds and different stars and planets. The clouds may cover all these in the sky temporarily, but this covering is only apparent to our limited vision. The sun, moon and stars are not actually covered. Similarly, maya cannot cover the Supreme Lord. By His internal potency He is not manifest to the less intelligent class of men.
One may question here that if Krishna is equal to everyone and no one is His special friend, then why does He take a special interest in the devotees who are always engaged in His transcendental service? But this is not discrimination; it is natural. Any man in this material world may be very charitably disposed, yet he has a special interest in his own children. The Lord claims that every living entity — in whatever form — is His son, and so He provides everyone with a generous supply of the necessities of life. He is just like a cloud which pours rain all over, regardless of whether it falls on rock or land or water. But for His devotees, He gives specific attention. Such devotees are mentioned here: they are always in Krishna consciousness, and therefore they are always transcendentally situated in Krishna.
