What are Sen lines?
Late lines are the invisible energy pathways of the body according to traditional Thai medicine. They can be compared to the meridians in Chinese medicine or the nadis in Indian Ayurveda. According to the theory, life energy – called “lom” – flows through these lines and affects both the body and mind.
When the energy in the Sen lines is blocked or does not flow freely, it can lead to physical symptoms, tension, fatigue or mental imbalances.
The 10 primary Sen lineages
Although the tradition mentions up to 72,000 Sen lines, Thai massage primarily focuses on 10 main lines. These energy pathways run throughout the body and are linked to important organs and functions:
- Late Sumana: The midline through the body – connected to breathing and heart
- Late Ittha and Pingkhala: Runs along the left and right sides respectively – balances masculine and feminine energy
- Late Kalathari: Passes through the arms and legs – often treated for muscle pain
- Late Sahatsangsi and Thawari: Relates to eyes and head
- Late Lawusang and Ulangka: Associated with stomach and digestion
- Late Nanthakrawat and Khitchanna: Affects genitals and excretion
Treatment along these Sen lines can restore balance and improve the overall energy flow in the body.
