A three-part cotton thread garland called a muppuri nool white is worn across the body, from the left shoulder to the right waist. Muppiri Nool is also known as Yajnopaveedam and Poonul.
- The goddesses Gayatri, Saraswati, and Savitri are represented by the three puris in Poonul. This serves as a constant reminder for the Poonula wearer to behave and think honestly.
- The old one should be taken off and the new one should be worn on Avani Avitam Day each year.
Yagno-pavita, which means "thread of sacrifice," represents the sacrifice of ego, rage, and selfishness.
