So by pious activities you can get all these things. And impious activities, the opposite number: in a family, abominable, pāpa-yoni, lower-grade family, not very beautiful, not educated, suffering in so many ways. So either you get this life or that life, the janma-mṛtyu-jarā-vyādhi is there. It is not that because you have got very beautiful body and born in very high-class family and highly educated, you will avoid janma-mṛtyu-jarā-vyādhi. That is not possible. The real problem is janma-mṛtyu-jarā-vyādhi.
So kāraṇaṁ guṇa-saṅgo 'sya sad-asad . . . sad-yoni (BG 13.22), high-class life, and asad-yoni, pāpa-yoni . . . so why one is born in lower grade family, why one is born in high-grade family? Kāraṇaṁ guṇa-saṅgo 'sya. The cause is as he has associated with different types of qualities. So unfortunately, this science, that there is birth after death, and there is . . . actually, we are experience; we are seeing. But they do not inquire. They think that one can improve. That is not possible. Unless he changes the quality, he cannot improve. That is not possible. They do not know it. They are falsely trying to improve the position. Nobody is trying to become poor. Everyone is trying to become rich. But it is not possible, because he has got a particular type of body, and that body is already destined, and he has to achieve happiness or suffer distresses according to the body.
Therefore śāstra says, tasyaiva hetoḥ prayateta kovido na labhyate yad bhramatām upary adhaḥ (SB 1.5.18): "You should try for that thing which you did not receive in your past lives." Past life, by our pious activities or impious activities, we have got a different type of body, here or in higher planetary system. That's all right. But that is not solution of my problem. The real problem is janma-mṛtyu-jarā-vyādhi (BG 13.9). So we should try, we should save time and utilize it, how to get out of this janma-mṛtyu-jarā-vyādhi. That is the whole Vedic civilization.
Therefore it is said, tasyaiva hetoḥ prayateta kovidaḥ. If you are intelligent, then you should try, you should engage your life, how to get out of this cycle of birth and death. Tapo divyaṁ putrakā yena śuddhyet sattvam (SB 5.5.1). We have to purify our existence so that we can revive our original position of eternal life, blissful life, full of knowledge. That is our requirement.
So modern civilization, they have no such information. Everyone is trying to improve his condition according to the quality. But that is not improvement. Real improvement is how to get out of this cycle of birth and death. That is real improvement. Janma-mṛtyu-jarā-vyādhi-duḥkha-doṣānudarśanam (BG 13.9).
