Is Meditation and Yoga instruction mandatory?
No, but it’s a great way to keep yourself in shape. You can read how to get started with Hatha Yoga here. The contraction and stretching of muscles during asanas promotes the movement of lymph in the body (a clear viscous fluid rich in immune cells). This allows the lymphatic system to better deal with infections, destroy cancer cells, and remove toxic waste from cells.
Yoga is great for improving your health.
