Singing repetition: Saa, Taa, Naa, Maa, (mantra)
With each syllable use the correct mudra (provided below)

Imagine the sound flowing in through the top of your head and out the middle of your forehead

For two minutes, sing in your normal voice
For the next two minutes sing in a whisper
For the next four minutes say the sound silently to yourself
Then reverse the order
Whispering for two minutes
Then normal voice for two minutes

To come out of the exercise, inhale very deeply, stretch your hands above your head, and then bring them down slowly in a sweeping motion as you exhale
The mudras, or finger positions, are very important in kirtan kriya and each sound is made with the following finger positions

Saa – Index finger touching thumb
Taa – Middle finger touching thumb
Naa – Ring finger touching thumb
Maa – Little finger touching thumb
