Veda References To Nadis
Though the system of Yoga had developed both in Vedic systems, this, in my opinion in the later Vedic period( as there is only one reference of Yoga describing Siva as Kesin), and in the Dravida Desa, South, both systems trace their origins to Siva and are essentially the same with minor differences.
Though the concept of Prana is found in Vedic texts there also some references of Nadi in Ancient Vedic texts. Nadi references are found in Tamil texts of Siddhas, Thirumandhiram and Texts dealing with Saiva Siddhandha to cite a few.
tube, pipe, nerve, blood vessel, pulse’) is a term for the channels through which, in traditional Indian medicine and spiritual knowledge, the energies such as prana of the physical body, the subtle body and the causal body are said to flow. Within this philosophical framework, the nadis are said to connect at special points of intensity, the chakras. All nadis are said to originate from one of two centres; the heart and the kanda, the latter being an egg-shaped bulb in the pelvic area, just below the navel.The three principal nadis run from the base of the spine to the head, and are the ida on the left, the sushumna in the centre, and the pingala on the right. Ultimately the goal is to unblock these nadis to bring liberation. https://en.m.wikipedia.org/wiki/Nadi_(yoga)
References in ancient Vedic texts.
- The nāḍis penetrate the body from the soles of the feet to the crown of the head. In them is prāṇa, the breath of life and in that life abides Ātman, which is the abode of Shakti, creatrix of the animate and inanimate world.-Varaha Upanishad.
- 3.6 “In the heart verily is Jivātma. Here a hundred and one nāḍis arise. For each of these nāḍis there are one hundred nāḍikās. For each of these there are thousands more. In these Vyâna moves.”
- 3.7 “Through one of these, the Udâna leads us upward by virtue of good deeds to the good worlds, by sin to the sinful worlds, by both to the worlds of men indeed.”-Prasna Upanishad.
- In the space outside the Meru, the right apart from the body placed on the left and the right, are the two nadis, Sasi and Mihira. The Nadi Susumna, whose substance is the threefold Gunas, is in the middle. She is the form of Moon, Sun, and Fire even water also; Her body, a string of blooming Dhatura flowers, extends from the middle of the Kanda to the Head, and the Vajra inside Her extends, shining, from the Medhra to the Head-Sat Chakra Nirupana. https://en.m.wikipedia.org/wiki/Nadi_(yoga)
gives an example of a tree with many parts like stem, branches, leaves etc. If one part is cut off from the main stream it would become dry. Similarly in our body these Nadis are spread horizontally and vertically from top to toe.Mahanarayan Upanishad also says the same. According toYoga Yajnavalkya, an ancient text on Yoga, the Nadis are spread in the body like the nerves in the leaves of the Peepal tree.https://www.google.com/amp/s/indianvedicheritage.wordpress.com/2016/01/10/surya-and-chandra-nadis-a-commentary/amp/
