What does the component 'Ujjayi' refer to in yoga?

The component 'Ujjayi' refers to a specific type of breath commonly used in yoga practice, characterized by a deep, audible breathing technique that involves slightly constricting the throat while inhaling and exhaling. This technique enhances the inward focus of the practitioner and helps to establish a rhythm in the practice, which can lead to a meditative state. It promotes greater oxygen intake and can help to maintain body heat during asana practice, contributing to overall vitality.

While other components of yoga, such as energy locks (bandhas), body postures (asanas), and mindfulness techniques (often practiced through meditation), play significant roles in yoga, Ujjayi specifically emphasizes breath control and deep, intentional breathing. Therefore, in the context of the question, Ujjayi is clearly defined as deep thoracic breathing, making it the correct choice.
