Maha Bandha – Great lock (Bestower of great siddhis)
Practice:
Sit in siddha or padmasana with the palms pressing on the knees. The spine should be straight. Breathe in slowly and deeply through the nose. Exhale forcefully and completely through the mouth. Hold the breath outside. Sequentially perform Jalandhara, Uddiyana and Moola Bandha at end. Inhale slowly when the head is upright. This is one round.
Benefits:
Maha Bandha gives the benefits of all three bandhas. It affects the hormonal secretions of the pineal gland and regulates the entire endocrine system. The decaying, cell of the body is rejuvenated. It soothes anger and introverts the mind prior to meditation. It leads to the merge of prana, apana and samana in agni mandala, which is the culmination of all pranayamas.
