Nadi Shuddhi (altornet nostril breathing) is an excellent practice that takes just 5 minutes to do. It reduces stress, balances energies, oxygenates blood, improves respiration, and calms you down. Often times if I do AUM chanting my voice is week and shaky. After I do Nadi Shuddhi my voice is strong and steady. June 21st is International Yoga Day. Yoga, especially pranayama (breath control), and meditation are exceptional landscapers of the the brain. In other words, they slowly and steadily make you mind more calm and clear and able to handle anxiety, anger, and depression if done regularly.
