Pitta is the biological energy of transformation. Composed of Fire and Water, it is the metabolic engine responsible for chemistry, heat regulation, and enzymatic breakdown.
While Vata provides motion, Pitta provides the heat necessary for change. It translates food into nutrients, perceptions into knowledge, and hormonal signals into physiological action. In modern terms, Pitta correlates with the Endocrine System and the Hepatobiliary (Liver/Bile) System.
The Five Sub-Doshas of Pitta
Pitta operates through five specialized sites of transformation (*Alokas*):

Cognition, emotional processing, willpower.
Alochaka Pitta

"पित्तं सस्नेह तीक्ष्ण उष्णं लघु विस्त्रं सरं द्र्वम्"
"Pittaṃ sasneha tīkṣṇa uṣṇaṃ laghu visraṃ saraṃ drvam"
Pitta is characterized by slight oiliness (sasneha), sharpness (tikshna), heat (ushna), lightness (laghu), malodorousness (visra), mobility (sara), and liquid nature (drava).
