Hatha yoga uses the physical postures (asanas), the breath (pranayama) e some techniques of meditation in order to free the vital energy of body and mind.
Stress, depression, worries, impure food and unhealthy surrounding atmosphere can contribute to create blocks of the prana (energy), that destroys our natural vitality and leads to disease.
Hatha Yoga helps to remove these blocks in order to purify the inner body and internal organs through physical and spiritual techniques, dominating the cosmic energy of the human being, manifested as breathing and therefore to achieve a steady control of the most unstable thing that can be imagined, our mind, always in rush and restless.
