The physical body is composed of eight ingredients known as mula prakriti:
manas- mind; buddhi- intellect; ahamkara ego/identification;
The five elements: akasha (space/ether);
vayu-air; agni- fire; apah- water; prithvi- earth.

The five elements form the three doshas, or basic humors in the body:
"Vayu" wind from the air element
"Pitta" bile from the fire element
"Kapha" mucos a combination of water and earth elements

There are also three gunas, or qualities, that operate through the doshas:
"Sattva" equanimity, lightness. "Rajas" passion. "Tamas" sloth, darkness.

The entire octave of prakriti exists within the human organism
"as in the macrocosm, so in the microcosm".
The connecting force of this whole network is


Vayu Prana, which operates through particular nadis
Pranavaha Nadi the carrier of pranic force,
Manovaha Nadi the carrier of mental force.
