Majja Vaha Srotas

The channel carrying nutrients for the bone marrow and nerve tissue is called majja vaha srotas. Its mula (root) is the brain, spinal cord, joints, and the junctions between dhatus. The marga (passage) is the central, sympathetic, and parasympathetic nervous systems. The mukha (opening or mouth) is the synaptic space. This srotas includes cavities of the bone, such as the auditory cavity and the spinal column. It is also connected to the emotions and to lacrimation, which is present in the eye orbit—there are tears of fear, anxiety, nervousness, anger, and frustration.

Ranjaka pitta is mainly present in the liver and the spleen. However, after a child is born, ranjaka agni is present in the bone marrow, while majja dhatu as nerve tissue is connected to sadhaka pitta for comprehension. Apana vayu and vyana vayu are present in the bones. The channel carrying bone marrow contains kledaka kapha, avalambaka kapha, prana vayu, vyana vayu, sadhaka pitta, and ranjaka pitta.

Majja vaha srotas also includes the nervous system, brain, spinal cord, and sensory and motor nerves. Their major function is to bring communication and to maintain the flow of intelligence and coordination. The governing doshic subtypes in majja vaha srotas as nerve tissue are prana vayu, sadhaka pitta, and tarpaka kapha.
