Ayurveda is a sister science to Yoga that focuses on inner and outer wellbeing through harmonizing (EACH OF THE 5) elements in the body.
According to this ancient science, each one of us exhibits a particular bio-energy that come together through the five elements (earth, water, fire, air, and ether) These are called 'doshas'.
There are three types of doshas Vata (air+ether), Pitta (fire+water), Kapha (earth+water) these combinations of the elements coalesce into three body-mind archetypes & dominate our physiological activities and also skin type.
At Shankara, we're primarily concerned about your three Ayurvedic skin types.
