A small experiment

Place your index finger just beneath your nostrils and exhale gently a few times. One side will usually feel stronger than the other. That is your dominant nostril.

For the next few days:

• Check your dominant nostril when you wake up.
• Repeat every two hours.
• Write down which side is active and notice when it changes.

When you complete the Centre phase, repeat the experiment. Has your breath begun to switch more naturally? Are both nostrils flowing more evenly?

Observe first. The breath reveals more than we think.
