So in this Bhagavad-gītā the subject matter is comprehending five different truths. The first truth is what is God. It is the preliminary study of the science of God. So that science of God is explained here. Next, the constitutional position of the living entities, jīva. Īśvara and jīva. The Lord, the Supreme Lord, He is called īśvara. Īśvara means controller, and jīva, the living entities are... Jīvas, the living entities, they are not īśvara, or the controller. They are controlled. Artificially, if I say that "I am not controlled, I am free," this is not the sign of a sane man. A living being is controlled in every respect. At least, in his conditioned life he is controlled. So in this Bhagavad-gita the subject matter comprehends about the īśvara, the supreme controller, and about the controlled living entities and prakṛti, the nature, the material nature. And next, the time, or duration of existence of the whole universe, or this manifestation of the material nature, and the duration of time, or the eternal time, and karma. Karma means activity. Everything, the whole universe, whole cosmic manifestation is full of different activities. The living beings especially, they are all engaged in different activities. So we have to study from the Bhagavad-gītā, īśvara, what is God, jīva, what are these living entities, and prakṛti, what is this cosmic manifestation, and how it is controlled by time, and what are these activities?
Now out of these five subject matter, in the Bhagavad-gītā it establish that the Supreme Godhead or Kṛṣṇa or Brahman or Paramātmā... You may call whatever you like. But the supreme controller. There is a supreme controller. So the supreme controller is the greatest of all. And the living beings, they are in quality like the supreme controller. Just like the supreme controller, the Lord, He has control over the universal affairs, over the material nature, how the... It will be explained in the later chapters of Bhagavad-gītā that this material nature is not independent. She is acting under the direction of the Supreme Lord. Mayādhyakṣeṇa prakṛtiḥ sūyate sa-carācaram (BG 9.10). "This material nature is working under My direction," mayādhyakṣeṇa, "under My superintendence." So we, we are mistaken. When we see wonderful things happening in the cosmic nature, we should know that behind these wonderful manifestations, there is a controller. Nothing can be manifested without being controlled. It is childish to, not to consider about the controller. Just like a very nice motor car with very good speed and very good engineering arrangement is running on the street. A child may think that "How this motor car is running without the help of any horse or any pulling agent?" But a sane man or an elderly person, he knows that in spite of all engineering arrangements in the motor car, without the driver it cannot move. That engineering arrangement of a motor car, or in electric powerhouse... Now at the present moment it is the day of machinery, but we should always know that behind the machinery, behind the wonderful working of the machinery, there is a driver. So the Supreme Lord is the driver, adhyakṣa. He is the Supreme Personality under whose direction everything is working. Now these jīva, or the living entities, they have been accepted by the Lord in this Bhagavad-gītā, as we'll know it in later chapters, that they are parts and parcels of the Supreme Lord. Mamaivāṁśo jīva-bhūtaḥ (BG 15.7). Aṁśa means parts and parcels. Now as a particle of gold is also particle, a drop of water of the ocean is also salty, similarly, we, the living entities, being part and parcels of the supreme controller, īśvara, Bhagavān, or Lord Śrī Kṛṣṇa, we have got, I mean to say, qualitatively all the qualities of the Supreme Lord in minute. Because we are minute īśvara, subordinate īśvara. We are also trying to control. We are just trying to control over the nature. In the present days you are trying to control over the space. You are trying to float imitation planets. So this tendency of controlling or creating is there because partially we have got that controlling tendency. But we should know that this tendency is not sufficient. We have the tendency of controlling over the material nature, lording it over the material nature, but we are not the supreme controller. So that thing is explained in the Bhagavad-gītā.
Then what is this material nature? The nature is also explained. The nature, material nature, is explained in the Bhagavad-gītā as inferior, inferior prakṛti. Inferior prakṛti, and the living entities are explained as the superior prakṛti. Prakṛti means which is controlled, which is under... Prakṛti, real meaning of prakṛti is a woman or a female. Just like a husband controls the activities of his wife, similarly, the prakṛti is also subordinate, predominated. The Lord, the Supreme Personality of Godhead, is the predominator, and this prakṛti, both the living entities and the material nature, they are different prakṛtis, or predominated, controlled by the Supreme. So according to Bhagavad-gītā, the living entities, although they are parts and parcels of the Supreme Lord, they are taken as prakṛti. It is clearly mentioned in the Seventh Chapter of the Bhagavad-gītā yes, apareyam itas tu viddhi aparā (BG 7.5). This material nature is aparā iyam. Itas tu, and beyond this there is another prakṛti. And what is that prakṛti? Jīva-bhūta, these...
So this prakṛti, the constitution of this prakṛti is constituted by three qualities: the mode of goodness, the mode of passion, and mode of ignorance. And above these modes, three different kinds of modes, goodness, passion, and, I mean to say, ignorance, there is eternal time. There is eternal time. And by combination of these modes of nature and under the control, under the purview of this eternal time, there are activities. There are activities, which is called karma. These activities are being done from time immemorial and we are suffering or enjoying the fruits of our activities. Just like in the present life also, we enjoy the activities, the fruits of our activities. Suppose I am a businessman and I have worked very hard with intelligence and I have amassed a vast amount of bank balance. Now I am the enjoyer. Similarly, suppose I started my business with a vast amount of money, but I failed to make a successful..., I lost all the money. So I am sufferer. So similarly, in every field of our life we enjoy, we enjoy the result of our work. This is called karma.
So these things, īśvara, jīva, prakṛti, or the Supreme Lord, or the living entity, the material nature, the eternal time, and our different activities, these things are explained in the Bhagavad-gītā. Now out of these five, the Lord, the living entities, and the material nature and time, these four items are eternal. Now manifestation, manifestation of prakṛti may be temporary, but it is not false. Some philosophers say that this manifestation of material nature is false, but according to the philosophy of Bhagavad-gītā or according to the philosophy of the Vaiṣṇavas, they do not accept the manifestation of the world as false. They accept that the manifestation is real, but it is temporary. It is just like a cloud takes place in the sky and the rainy season begins, and after the rainy season there are so many new green vegetation all over the field, we can see. And as soon as the rainy season is finished, then the cloud is vanquished. Generally, gradually, all this vegetation dry up and again the land becomes barren. Similarly, this material manifestation takes place at a certain interval. We'll understand it, we'll know it, from the pages of the Bhagavad-gītā. Bhūtvā bhūtvā pralīyate (BG 8.19). This manifestation becomes magnificent at a certain interval, and again it disappears. That is the work of the prakṛti. But it is working eternally; therefore prakṛti is eternal. It is not false. Because the Lord has accepted, mama prakṛti, "My prakṛti." Apareyam itas tu viddhi me prakṛtiṁ parām (BG 7.5). Bhinnā prakṛti, bhinnā prakṛti, aparā prakṛti, this material nature is a separated energy of the Supreme Lord, and the living entities, they are also energy of the Supreme Lord, but they are not separated. They are eternally related. So the Lord, the living entity, the nature, material nature, and time, they are all eternal. But the other item, karma, is not eternal. The effects of karma or activity may be very old. We are suffering or enjoying the results of our activities from a time immemorial, but still, we can change the result of our karma, or activity. That will depend on our perfect knowledge. We are engaged in various activities undoubtedly, but we do not know what sort of activities we shall adopt that will give us relief from the actions and reactions of all activities. That is also explained in the Bhagavad-gītā.
Now, the position of īśvara is supreme consciousness. Position of īśvara, or the Supreme Lord, is supreme consciousness. And the jīvas, or the living entities, being parts and parcels of the Supreme Lord, he is also conscious. A living entity is also conscious. The living entity is explained as prakṛti, energy, and the material nature is also explained as prakṛti, but amongst the two, one prakṛti, the jīvas, they are conscious. The other prakṛti is not conscious. That is the difference. Therefore the jīva prakṛti is called superior because the jīvas has consciousness similar to the Lord. The Lord is supreme consciousness. One should not claim that a jīva, a living entity is also supremely conscious. No. A living being cannot be supremely conscious at any stage of his perfection. This is a misleading theory. This is misleading theory. But he is conscious. That's all. But he is not supreme conscious.
The supreme conscious, it will be explained in the Bhagavad-gītā in the chapter where the distinction between the jīva and īśvara is explained. Kṣetra-kṣetra-jña. This kṣetra-jña has been explained that the Lord is also kṣetra-jña, or conscious, and the jīvas, or the living beings, they are also conscious. But the difference is that a living being is conscious within his limited body, but the Lord is conscious of all bodies. Īśvaraḥ sarva-bhūtānāṁ hṛd-deśe 'rjuna tiṣṭhati (BG 18.61). The Lord lives within the core of heart in every living being, therefore He is conscious of the psychic movements, activities, of the particular jīva. We should not forget. It is also explained that the Paramātmā, or the Supreme Personality of Godhead, is living in everyone's heart as īśvara, as the controller and He is giving direction. He is giving direction. Sarvasya cāhaṁ hṛdi sanniviṣṭhaḥ (BG 15.15), everyone's heart He is situated, and He gives direction to act as he desires. The living entity forgets what to do. First of all he makes his determination to act in a certain way, and then he is entangled in the actions and reactions of his own karma. But after giving up one type of body, when he enters another type of body... Just like we give up one kind of dress, one type of dress, for another type of dress, similarly, it is explained in this Bhagavad-gītā that vāsāṁsi jīrṇāni yathā vihāya (BG 2.22). One, as one changes his different dresses, similarly the living entities, they are also changing different bodies, transmigration of the soul, and pulling on the actions and reactions of his past activities. So these activities can be changed when a living being is in the mode of goodness, in sanity, and he understands what sort of activities he should adopt, and if he does so, then the whole action and reactions of his past activities can be changed. Therefore karma is not eternal. Other things, out of the four, five items—īśvara, jīva, prakṛti, kāla, and karma—these four items are eternal, whereas the karma, the item known as karma, that is not eternal.
