Step 1: Uddiyana Bandha Explained
Uddiyana Bandha, or abdominal lock, is a yogic technique. It involves lifting the diaphragm and drawing the abdominal muscles inward and upward after a complete exhalation, creating a hollow space beneath the rib cage. While primarily an abdominal practice, the tongue's position also contributes to the overall bandha.
Step 2: Tongue Positioning in Uddiyana
When Uddiyana Bandha is performed, particularly with other mudras or pranayama, the tongue is often curled backward. This action, sometimes referred to as Jihva Bandha or Khechari Mudra, results in a tongue shape described as similar to a fresh, curled leaf.
Step 3: Disregarding Other Techniques
- Bhramari is a humming practice with no specific tongue posture.
- Sheetkari and Sitali are cooling pranayamas. While the tongue may be rolled, it does not adopt the "fresh curled leaf" shape.
Step 4: Conclusion
Therefore, the correct answer is Uddiyana, as it is the practice that features the curled tongue posture.
