So vāsudeva-parā yogā vāsudeva-parā kriyāḥ. All the activities should be... The same thing. Kriyā means varṇāśrama-dharma, everyone is engaged in his own work. Brāhmaṇa is engaged in his own work. Kṣatriya is engaged in his own work. That is all right. But the ultimate goal should be hari-toṣaṇam. Svanuṣṭhitasya dharmasya. It doesn't matter whether you are brāhmaṇa or a kṣatriya or a vaiśya and śūdra. It doesn't matter. Just try to see by your work whether Kṛṣṇa or Vāsudeva is being satisfied. Vāsudeva-parā kriyāḥ. Vāsudeva-paraṁ jñānam. Jñānam, cultivation of knowledge. What is that cultivation of knowledge? To understand Vāsudeva. Therefore Kṛṣṇa says bahūnāṁ janmanām ante (BG 7.19). So-called knowledge, speculation, philosophical speculation, without understanding of Vāsudeva, means he has to continue such speculation for life after life. Therefore Kṛṣṇa says, manuṣyāṇāṁ sahasreṣu kaścid yatati siddhaye (BG 7.3). Jñānam, jñānam means knowledge. So if you immediately take to Vāsudeva... Bhakti-yogaḥ prayojitaḥ (SB 1.2.7). Vāsudeve bhakti-yogaḥ prayojitaḥ, janayaty āśu vairāgyaṁ jñānaṁ ca. The ultimate goal of knowledge is to know Vāsudeva, but if you take to Vāsudeva directly, then vairāgya and jñāna... Janayaty āśu vairāgyam jñānam. Immediately, very soon, automatically, ahaitukam, without any cause, you understand what is knowledge and what is vairāgya.
So vāsudeva-paraṁ jñānam. All scientific research should be to know Vāsudeva. In Boston I was invited in the Massachusetts Technological Institute? Yes. So I, first of all I questioned the students that "You have got technological department. So where is the technology where we can understand the difference between a dead man and a living man? What is the thing is lost that a body's called dead body? What is that technology." So I talked on this point. The students appreciated very much. Actually, there is no technology why a man is dead. What is the machine, what is the component part of the machine is missing? You can replace it. But where is that technology? There is no technology. Because there is no knowledge with reference to Vāsudeva. Simply superficial. Bahir-artha-māninaḥ. They do not know what is the purpose of knowledge. They're taking interest, taking care of this bahir-artha, external things. Bahir-artha-māninaḥ. Na te viduḥ svārtha-gatiṁ hi viṣṇum (SB 7.5.31). This is knowledge, svārtha-gatim, to approach Vāsudeva, Viṣṇu. But without that knowledge, they are simply taking outward. Just like Darwin's theory. He has no knowledge. He's simply studying this body. That's all.
