Ashtanga Yoga is a traditional system of yoga that was popularized by K. Pattabhi Jois in the 20th century. The practice is based on a set sequence of postures, which are performed in a continuous, flowing sequence known as a vinyasa. Ashtanga Yoga is a physically demanding practice that emphasizes strength, flexibility, and endurance. The practice of Ashtanga Yoga is divided into six series, each of which is more advanced than the previous one. The first series, known as the Primary Series, is the foundation of the practice and consists of approximately 75 postures. The other five series build on the Primary Series and include more challenging postures. Ashtanga Yoga is often referred to as a "moving meditation" because of the emphasis on linking breath with movement. The practice is also known for its emphasis on drishti, or gaze, which helps to focus the mind and cultivate concentration. In addition to the physical benefits, Ashtanga Yoga is also said to have a profound effect on the mind and spirit. Practitioners often report feeling more calm, centered, and focused after a practice. Overall, Ashtanga Yoga is a powerful practice that can help to cultivate strength, flexibility, and mindfulness. While it is a challenging practice, it is accessible to people of all levels and can be adapted to meet the needs of each individual practitioner.
