Nadis in Tantric Literature

The term Nadi is the most controversial term in the field of Ayurveda & Yoga. It is not an easy subject & cannot be understood by studying Ayurveda texts. To get into the depth it is necessary to consult texts on Nervous system, Psychology, Ayurveda, Tantra, Acupuncture in addition to Yoga texts. Nadi means stream in Rig-veda. It is very important to understand this term “Stream” on which the whole concept of Nadi stands. In other words we can say that, any channel through which energy flows is Nadi. Yogis did least anatomical correlations on this subject as this was known to all at that time as these are the principle path or tract through which consciousness travels or it was not much necessary for them. The conducting pathways are quoted by Tantric as well as Yogic Gurus, but they give this in a different way. Since they are made up of subtle matter they cannot be seen by naked eyes & we cannot make any test at this level to show scientifically these are those nerves which we met when we do the dissection of Human body. So the quest of “Nerves” in the physical body can be clearly identified, but those Nadis or Nerves in the astral body is yet to be identified
