Nadi Shodhana
Purification of the energy channels. It is a fundamental pranayama technique that cleanses the nadis, especially ida, pingala, and sushumna.
The classical practice alternates breathing between nostrils, balancing the solar and lunar energies of the body. This balance is a prerequisite for prana to flow through sushumna, the central channel.
The Haṭha Yoga Pradīpikā emphasizes that without purified nadis, kundalini awakening is not possible. Therefore, nadi shodhana is considered essential preparatory practice.
