Pitta is the principle of transformation.
Kapha the principle of structure, cohesion and lubrication. For more information on the Doshas and basic information on Ayurveda we recommend The Wisdom of Healing by David Simon, Perfect Health by Deepak Chopra, and The Book of Ayurveda by Judith Morrison. In order that the five actions are performed correctly it is vital that a qualified Ayurvedic doctor gives the treatment. An inexperienced professional can do more harm than good. Poorva Karma Poorva Karma, Preparatory Procedures, is designed to prepare the body for elimination of imbalances.
