Right Ear Nadanusandhana in Hatha Yoga Pradipika

Regarding the Nadanusandhana practice in the 4th chapter of Hatha Yoga Pradipika, in verse 4.66 or 4.67, "the right ear" is mentioned.
I would like to know if this translation refers to the "correct" ear or to the "right side".
Right can mean two things: not the left side or the proper/correct ear.
Please, somebody that can translate this sanskrit word right. Thank you.

Nadanusandhana is a term used in yoga and refers to the practice of listening to internal sounds, also known as nada yoga. In Hatha Yoga Pradipika, an ancient text on hatha yoga, it is mentioned that practicing Nadanusandhana, specifically in the right ear, can help to awaken the kundalini energy and improve concentration.

The Hatha Yoga Pradipika states that to practice Nadanusandhana, one should sit in a comfortable seated posture with the spine erect and the eyes closed. Then, the practitioner should focus their attention on the right ear, listening to the internal sounds that arise. These internal sounds may include the sound of the breath, the sound of the blood flowing through the veins, or other subtle sounds.

According to the text, practicing Nadanusandhana in the right ear can help to activate the pingala nadi, which is one of the three main energy channels in the body. The pingala nadi is associated with the solar energy, or the energy of action, and is said to be responsible for awakening the kundalini energy.

While Nadanusandhana may not be a common practice in modern yoga classes, it is still considered a valuable technique for those seeking to deepen their meditation practice and awaken their inner energy. It is important to note, however, that the practice should be approached with caution and under the guidance of an experienced teacher, as it can be intense and potentially harmful if not practiced correctly.
