The bee breath soothes the nerves and calms the mind.
Inhale through both nostrils, taking a slow deep breath in. Exhale through both nostrils using the throat to make a soft "eeee" sound, like the buzzing of a bee. Do 5-10 rounds, making the buzzing bee noise louder as you progress, but do not strain.
Block off the right nostril with the thumb using visnu mudra (as in nadi sodhna pranayama) and inhale through the left nostril using Ujjayi pranayama. Exhale through the left nostril using the throat to make a soft "eeee" sound, like the buzzing of a bee. Block off the left nostril and repeat on other side, practicing for 5-10 rounds.
