Ladies are Practicing the Jnana and or chin mudra. When fingers point up it is called Jnana, when fingers point down towards the earth it is called chin mudra. You allow the tips of the thumb and index finger to touch each other and extend your other fingers. It is a passive receiving position. It is one of the best known hand positions of Hatha yoga. The gesture symbolizes the connection of human consciousness. The shape of the circle made by the index finger and thumb represent one of the many goals of yoga, which is the unification of the individual soul and the world soul. It helps improve mental tension and stimulates concentration.
Practice as you like. See as you like. You will see what you practice, and you will practice what you see.
