Esoteric science studies five fundamental elements in nature, which are manifestations of more subtle energetic sources called tattvas.
- 1. ether (related to the tattva akash)
- 2. fire (related to the tattva tejas)
- 3. air (related to the tattva vayu)
- 4. water (related to the tattva apas)
- 5. earth (related to the tattva prithvi)
"From Atman did space [akash] come into being;
from space, air;
from air, fire;
from fire, the waters,
from the waters, the earth;
from the earth, plants;
from plants, food;
and from food, man..." - Hinduism: Taittirīya Upaniṣhad
