Kaki Mudra

Nostril Breathing is for upper part.

Mouth Breathing is for lower abdomen heat.

Mouth breathing helps cooling down abdomen heat and converting or cool down emotions and stress which may further cause Tamas. Shouldn't be done more than 5-6 breaths otherwise cause emotions to go up and erupts instantly.

Kaki Mudra, also known as the Crow’s Beak Gesture, is a yogic breathing technique (pranayama) and mudra where the lips are pursed to imitate the shape of a crow's beak. It is primarily used to cool the body, improve digestion, and promote longevity. 

How to Practice Kaki Mudra

1. Posture: Sit in a comfortable meditative pose (like Sukhasana or Vajrasana) with your spine erect and hands resting on your knees.
2. Mouth Positioning: Purse your lips to form a small, round opening resembling a beak.
3. Gaze (Drishti): Focus your eyes on the tip of your nose (Nasikagra Drishti).
4. Inhalation: Inhale slowly and deeply through the pursed lips, feeling the cool air enter.
5. Exhalation: Close your mouth and exhale slowly through your nostrils.
6. Duration: Repeat for 5–10 rounds, or for 2–5 minutes.
