The nadis are well knowed for those who practice yoga. Their challenge is to move energy through the nadis to feed their physical, mental, and spiritual development.
The nadis are our energetic irrigation system.
The Sanskrit word nadi means “flow,” “motion,” or “vibration.”
The fundamental nature of a nadi is to flow, to find inside the body the path of least resistance and nourish everything in its path.
This is the most common way to display Ida & Pingala nadis.
a book from Tony CERON, each chakra is related to a musical note.
This approach of Tony CERON is related to alchemy and planets.
The same relationship between chakras and music notes is used by Michel LARROCHE in its
"CELLULAR ANALYSIS AND REINFORMATION" practice (using musical tuning forks).
