Fingers positioning is very similar to the previous mudra, but instead of curling the middle and index finger inside, you keep them straight and rest on your forehead. You still use thumb and ring finger to press the nostrils. Placing the finger on the forehead is associated with Ajna chakra – the third eye, the seat of intuition and insights. Using this mudra aids to concentration in pranayama and has a calming effect.
Even though in Pranayama you use your right hand, in longer practices it may become tiring to hold it up. You may then switch your hands gently, without interrupting your practice. Today, during the next level of Nadi Shodhana practice, try using one of the mudras you just learned.
