Yoga physiology are the descriptions of the human body, its layers, and the energy channels running through it used in various yoga systems.
DIALOGUE BETWEEN SHIVA AND PARVATHI (OLD HISTORY): According to a story in the puranas, Lord Shiva was instructing parvati into the secret sadhanas of yoga while standing on the seashore. A large fish overheard all that said and from this fish, all knowing Matsyendranath was born. Hence his name Matsya - Indra or 'Lord of fish'. There are also many stories concerning the birth of Goraknath. It is said that when Matsyendranath was begging for food as a parivrajaka, he met a woman who lamented to him her woe of not having a son. Matsyendranath gave her some siddha vibhooti and told her that if she eats it, she would obtain a son. The woman did not eat that substance but cast it upon a pile of cowdung. Twelve years later, when Matsyendranath was passing through the same village, he called her to see the child. The woman told the yogi what she had done and he asked to be taken to the spot where she had thrown the vibhooti. He called the name 'Gorkhnath' and immediately a radiant twelve-year-old lad emerged from the pile of cow dung. Gorkhnath became the dutiful disciple of Matsyendranath and later became an expounder of hatha yoga and the founder of the Nath sect. He was an accomplished guru credited with the performance of many miracles. Gorkhantha, who was probably the guru of Swatmarama, belonged to a very popular yoga sect called the Nath panth. Nath is a general term meaning 'master'. Members of these are Kanphata yogis. Kanphata means 'split-eared' and refers to the yogis' unique practice of having the cartilage of the ears pierced for the insertion of huge earrings.
Yoga (Sanskrit: योग About this sound pronunciation (help·info)) are the physical, mental, and spiritual practices or disciplines which aim at transforming body and mind. The term denotes a variety of schools, practices and goals in Hinduism, Buddhism (including Vajrayana and Tibetan Buddhism) and Jainism, the best-known being Hatha yoga and Raja yoga. The term yoga is derived from the literal meaning of Sanskrit root "yuj" which means "to unite" ,Template:Monier Monier-Williams.

The origins of Yoga may date back to pre-vedic Indian traditions. The earliest accounts of yoga-practices are to be found in the Buddhist Nikayas. Parallel developments were recorded around 400 CE in the Yoga Sutras of Patanjali, which combines pre–philosophical speculations and diverse ascetic practices of the first millennium BCE with Samkhya-philosophy. Hatha yoga emerged from tantra by the turn of the first millennium.
Three bodies and five sheets
According to the Doctrine of the Three bodies in the Vedanta and Yoga, the human being is composed of three Sariras or "bodies". They are often equated with the five koshas (sheets), described in the Taittiriya Upanishad which cover the Atman or "Self". They are:
- Sthula sarira, the Gross body, composed of the Annamaya Kosha
- Suksma sarira, the Subtle body, composed of:
- Karana sarira, the Causal body, composed of the Anandamaya Kosha (Bliss)
Karana sarira is the cause of Sthula sarira and Suksma sarira.
Chakras are energy centers or vortices in the subtle body. They are located at the physical counterparts of the major plexuses of arteries, veins and nerves. Chakras are part of the subtle body, not the physical body, and as such are the meeting points of the subtle (non-physical) energy channels, called nadiis. Nadiis are channels in the subtle body through which the life force (prana), or vital energy moves. Various scriptural texts and teachings present a different number of chakras. There are many chakras in the subtle human body according to the tantric texts, but there are 7 chakras that are considered to be the most important ones.
Nāḍi (tube, pipe") are the channels through which, in traditional Indian medicine and spiritual science, the energies of the subtle body are said to flow. They connect at special points of intensity called chakras.
The word "nadi" is pronounced as "naRdi", with R+d loosely pronounced together (the effort is made by the tip of the tongue; it curls up, pointing backwards, then springs forward to lie flat). In normal biological reference, a nadi can be translated into "nerve" in English. However, in yogic, and specifically in Kundalini yoga reference, a nadi can be thought of as a channel (not an anatomical structure). In regard to Kundalini yoga, there are three of these nadis: Ida, pingala, and sushumna. Ida (spoken "iRda") lies to the left of the spine, whereas pingala is to the right side of the spine, mirroring the ida. Sushumna runs along the spinal cord in the center, through the seven chakras – Mooladhaar at the base, and Sahasrar at the top (or crown) of the head. It is at the base of this sushumna where the Kundalini lies coiled in three and a half coils, in a dormant or sleeping state.
