By pious activities, you can be raised to the position of Brahmā, Indra, Candra, demigods, big, big demigods. And by impious activities, you can go down to become the worm of a stool. This is going on. This is called bhramatām upary adhaḥ. Upari adhaḥ. Adhaḥ means down, and upari means up. So ūrdhvaṁ gacchanti sattva-sthāḥ (BG 14.18). Who are going to upper planetary system? Sattva-sthāḥ, those who are qualified brāhmaṇas, strictly following the principles.
- śamo damas tapaḥ śaucaṁ
- kṣāntir ārjavam eva ca
- jñānaṁ vijñānam āstikyaṁ
- brahma-karma svabhāva-jam
- (BG 18.42)
If you follow these principles, controlling the senses, truthful, clean, full of knowledge, believing in the śāstra and God, and vijñānam, practical application of knowledge in life. Vijñānam... Simply to know is useless. You must practically apply in life. That is called vijñānam. Practical examination.
