Most American boys and girls, they are all beautiful. So why this position? This position is due to puṇya, karma. Karma means pāpa-karma, puṇya-karma. This is the way. Karmaṇā daiva-netreṇa jantur dehopapattaye (SB 3.31.1). This is said in the Śrīmad-Bhāgavatam. By karma, the janta, the living entity, jantu, he is getting a particular type of body. In Bhagavad-gītā also it is stated that kāraṇaṁ guṇa-saṅgo 'sya. Prakṛteḥ kriyamāṇāni guṇaiḥ karmāṇi sarvaśaḥ (BG 3.27). Kāraṇaṁ guṇa-saṅgo 'sya sad-asad-janma-yoniṣu (BG 13.22). We are associating with a particular type of modes of nature—goodness, passion and ignorance, or mixed. So on account of this, we are working differently and we are preparing our next life, kāraṇam. This is the kāraṇam.
So those who are karma-kāṇḍīya, they are interested next life in the heavenly planet or higher standard of life. So that is also stated in the Bhagavad-gītā. Ūrdhvaṁ gacchanti sattva-sthāḥ (BG 14.18). If you associate with the modes of goodness, then you are promoted to the higher planetary system, beyond heavenly planets: Janaloka, Tapoloka, Maharloka, Satyaloka, Siddhaloka, Brahmaloka. So that is possible. But our problem is not to promote ourself to go to the heavenly planet or higher than that, Janaloka, Satyaloka, Maharloka or Brahmaloka. Kṛṣṇa advises, ā-brahma-bhuvanāl lokāḥ punar āvartino 'rjuna (BG 8.16). He does not encourage that, "You go to the Brahmaloka." No. He never encourages. He says, ā-brahma-bhuvanāl lokāḥ punar āvartino 'rjuna (BG 8.16). Even if you become promoted to the Brahmaloka, then again you have to come back. Kṣīṇe puṇye punar martya-lokaṁ viśanti. As soon as your puṇya, the duration of life, is finished, then you have to come back again. This is going on.
