Final answer:
Repeating a phrase or word, known as a mantra, during yoga helps enhance concentration and elicit emotions, done in a comfortable seated position in a peaceful environment.
Step-by-step explanation:
The technique of repeating a phrase or word during a yoga class to enhance concentration or elicit a specific emotion is known as using a mantra. This method involves sitting upright in a comfortable position with the feet on the ground, preferably in a peaceful setting, and with the eyes closed. Mantras, such as "Let go" or "I am enough", are repeated silently or aloud, helping the individual maintain focus and achieve a calm state. This practice aids in centering the mind on positive, soothing thoughts and is a vital aspect of a yoga routine that can enhance the overall experience.
