So here it is said, therefore, dravya-sphuraṇa-vijñānam. Dravya means physical. Dravya-jñāna. Dravya-jñāna means physical knowledge. And brahma-jñāna means spiritual knowledge. So here it is said, dravya-sphuraṇa. The material, physical, phenomenal atmosphere is developing one after another. The medical science, they are trying to study different cells; but wherefrom the cells came into action? That is by the influence or by the manipulation of prakṛti. Prakṛteḥ kriyamāṇāni (BG 3.27). And prakṛti is working under the direction of Supreme Lord, Kṛṣṇa. Mayādhyakṣeṇa prakṛtiḥ (BG 9.10). Therefore, ultimately, by the superintendence of the Supreme Personality of Godhead everything is going on. But how it is going on, that we cannot explain. We have got limited knowledge. Therefore śāstra says, "Don't try to speculate, because you are imperfect, but things are going on like this." Try to understand. Acintyāḥ khalu ye bhāvā na tāṁs tarkeṇa yo... Simply by your so-called argument and logic you cannot understand. You have to hear from the authorities that "Things are going on like this."
This is called śruti, Veda-jñāna. Śruti, Veda, perfect knowledge is called śruti. Śrutibhiḥ pratipanna, pratipanna. What is established by the śruti, by the Vedic knowledge, that we have to accept. Otherwise there is no other way. So this is even in the material field of activities, and what to speak of the spiritual. Therefore we have to hear from the authorities of śruti. Authorities of śruti... Kṛṣṇa is the original speaker of śruti, or Veda knowledge. Therefore Vedic knowledge is called apauruṣeya. It is not manufactured or concocted by some mental speculator. It is coming from the Supreme Personality of Godhead, and it was imparted first of all to Lord Brahmā, not by personal presentation, but through the heart. Brahmā is the original person to understand Vedic knowledge. So after his birth he meditated for hundreds of years, and by meditation, through his heart the knowledge of Vedas, śruti, became revealed. Tene brahma hṛdā ādi-kavaye. Ādi-kavi means Brahmā. And Brahman means Vedic knowledge. So we have to accept in that way. There is no physical science which can ascertain all this, how the things are taking place. But they are coming. In this way we have to learn from the śruti. Dravya-sphuraṇa-vijñānam indriyāṇām anugrahaḥ.
So dravya, the physical body, that is influenced by the taijasāt vikurvāṇāt . This physical body is developed by the mode of passion, the ego. The false ego of the spirit soul, when it is influenced by the mode of passion, then these indriyas, different indriyas, senses-eyes, ear, nose, tongue, hands, legs, genital, rectum—all these things—nine chidras, holes in the body—develop. And they ultimately come to become the different parts and limbs of the senses of the body.
- taijasāt tu vikurvāṇād
- buddhi-tattvam abhūt sati
- dravya-sphuraṇa-vijñānam
- indriyāṇām anugrahaḥ
In this way the senses came into being. And we have discussed last night the all this controlling is going on under the supervision of Aniruddha. Aniruddha is in charge of development of these indriya also. Indriyāṇām adhīśvaram. Yad vidur hy aniruddha-ākhyaṁ hṛṣīkāṇām adhīśvaram. Hṛṣīka means the indriya, or the senses. So actually we have discussed already. We are simply under some machine. Bhrāmayan sarva-bhūtāni yantrārūḍhāni (BG 18.61). A machine is manufactured immediately. Just like your medical men. They also manufacture some skeleton according to the requirement of the patient. So this body is manufactured by the supervision of the Supreme Personality of Godhead and the ingredients given by material nature, and I am put into the machine. This is my position. As I desire to enjoy... Actually, I haven't got to enjoy or reject anything. I am put into a certain type of machine, and I have to go or work. Actually, I do not also work. The work is also going on by different agents. I am simply put into it just to satisfy my desires as I wanted. Ye yathā māṁ prapadyante tāṁs tathaiva bhajāmy aham (BG 4.11). Kṛṣṇa is so kind that He has given us the chance of enjoying.
