Yoga makes a re-arrangement... it strengthens your body and makes it capable to solve all the problems by itself.
Yoga is a form of Sadhana, or spiritual practice for the purpose of self-realization. Yoga is not perceived in the West to address ailments per se, and this is largely due to the fact it is practiced separately from Ayurveda. Yoga in a therapeutic context is essentially Ayurvedic in nature.
Using Ayurveda along with Yoga helps us gain complete harmony and balance in body and mind so that we can discover our true Self that is one with all.
