Navama-prakaraṇam (Samādhi) · Verse 9

प्राणोऽपानः समानश्च उदानो व्यान एव च । नागः कूर्मो वराहश्च कृकरो धनञ्जयः ॥

prāṇo'pānaḥ samānaśca udāno vyāna eva ca | nāgaḥ kūrmo varāhaśca kṛkaro dhanañjayaḥ ||

This verse meticulously delineates the five prāṇasprāṇa, apāna, samāna, udāna, and vyāna – each intimately associated with specific physiological locations. The enumeration of these prāṇasnāga (associated with the spine), kūrma (linked to the stomach), varāha (connected to the solar plexus), krikara (related to the spleen), and dhananjaya (associated with the liver) – provides a detailed anatomical framework for understanding the subtle energetic currents within the body. These five primary prāṇas are not merely breath; they represent the vital force governing all bodily processes, from digestion (apāna) to respiration (prāṇa), and their precise localization is crucial for cultivating balance and directing prāṇic energy. The yogi’s ability to consciously manipulate these flows through prāṇāyāma and other practices ultimately serves as the foundation for achieving samādhi and liberation.
