This is the test: na māṁ prapadyante. Kṛṣṇa says: "Who does not surrender to Me? They are these classes of men." What is that? Duṣkṛtinaḥ: "Always engaged in sinful activities." Kṛti means meritorious. But they are engaged in manufacturing atom bomb, duṣkṛtinaḥ. Atom bomb means killing. But discover something by which man will not die. That they are dying—so you have discovered some instrument to die quickly. So that is duṣkṛtinaḥ. Merit, he has got merit, but misuse the merit. The death is there. He would have lived for, say, sixty years, and you drop atom bomb—in ten years or twenty years, finished. You cannot increase the duration of life. Therefore the so-called scientific, I mean to say, advancement, what is that? Duṣkṛtinaḥ: no benefit for the human society.
The real problem is, Kṛṣṇa says in the Bhagavad-gītā, janma-mṛtyu-jarā-vyādhi-duḥkha-doṣānudarśanam (BG 13.9). Our real miserable condition of life is birth, death, old age and disease. Where is scientific help to mitigate these miseries? There is no stoppage of birth; there is no stoppage of death; there is no stoppage of disease. You can manufacture very good medicine for disease, but you stop disease. That is not possible. So our so-called meritorious activities in scientific research and education, they have been described in the Bhagavad-gītā as duṣkṛtinaḥ, mischievous activities. Duṣkṛtinaḥ. They are not actually beneficial, but they are mischievous. And why, mischievous, they are engaged, they are wasting their so much time in mischievous? Because mūḍhāḥ: they do not know what is the purpose of life.
