The term ‘Katakamukha’ refers to ‘opening in a bracelet’ and it forms one of the significant mudras in Natyashastra.
In Bharatanatyam, Katakamukha mudra can be shown in three different ways.
Here, the index finger, the middle finger, and the thumb are brought together. The mudra is used to demonstrate holding or plucking flowers, wearing a necklace, and often talking or seeing.
