Patanjali had achieved the state of samadhi, which refers to an experience of oceanic or divine ecstasy. Today the term ecstasy often connotes a drug-induced stateof euphoria or the peak of sexual pleasure, but there is a passage in the scriptures where in samadhi is said to have about a trillion times the intensity of sexual pleasure. In other words, it is far beyond anything you can imagine in normal experience. Because he existed continually in this state of absolute freedom, Patanjali described a path that could lead all of us to it. He asked himself, Which state immediately precedes divine ecstasy? The answer was meditation (dhyana). Samadhiis our true nature, but we cannot receive it if our minds are too busy to listen, he reasoned; therefore, the path to samadhi lies in quieting the mind, which isaccomplished when one achieves the state of
Agni
Agni represents the inner fire in yoga. Accordingly, the sushumna, visualized red, is called the fire nadi. Inner fire is created through ritualistic practice (tapas)such as asana. The term tapas is derived from the verb root tap, to cook. Inner heat, produced by correct forms of exertion, is used to burn toxins and impurities.such as asana. The term tapas is derived from the verb root tap, to cook. Inner heat, produced by correct forms of exertion, is used to burn toxins and impurities.Any such activity brings about sweat, which is the water produced by the heated body.14 Sweat has an important function in yoga. Shri B.N. S. Iyengar
repeatedly instructed me that “sweat goes to the next life.” This means, on one hand, that the fruit produced by right exertion is not lost when the mortal body is shed; and onthe other hand, that creative power is ascribed to the sweat itself. In the Puranas there are several incidences of procreation happening when a drop of sweat falls offthe brow of a celestial or rishi, and a new powerful being springs up from it. Procreation in the Golden Age (Satya Yuga) was thought to be possible withoutintercourse; the father merely wiped the sweat off his brow and rubbed it on the skin of his wife. Finally, the medieval Hatha texts inform us that the sweat producedby practice should not be wiped off but rubbed back into the skin. By this method, inner glow (tejas) is restored. Tejas is another form of Agni.
The origin of yoga
The Supreme Being in the form of Lord Shiva is credited with the authorship of yoga (in the Mahabharata, Shiva is called Yogeshvara, Lord of Yoga) because many myths about the origin of yoga start with a dialogue between him and the mother of the universe, Uma Parvati, often called Shakti.On one occasion when the Lord was teaching, the serpent of infinity, Ananta, was hiding close by and eaves dropped on the secret teaching. (Of course,Ananta is yet another aspect of the same Supreme Being, manifesting for the promulgation of the eternal teaching.) After he had heard enough, Ananta tried to slither away undetected, but Shiva apprehended him, having been aware of his presence all along. For his transgression, he sentenced Ananta to the task of relating this secret teaching (yoga) to the human beings. Ananta, the one-thousand-headed celestial cobra, then approached the next human village in his new found role as ambassador of yoga.
However, the Indian villagers — who didn’t take too kindly to the appearance of normal, one-headedcobras, much less one-thousand-headed ones — pelted Ananta with stones. Ananta returned to Lord Shiva for advice, and the Lord suggested he take ona human form. After doing so, he succeeded in teaching yoga to human beings. This incident is still remembered today in the second pada of the opening prayer of the Ashtanga Vinyasa practice. It says, “abahu purushakaram,” which means, “to him who is of human form from the arms upward.” It also says, “sahasrashirasam shvetam,” which means “one thousand white heads.” This is to acknowledge the fact that Ananta, the one-thousand-headedserpent of infinity, took on a human form and was called Patanjali. To reflect this, Patanjali is depicted as a human torso placed on the coils of a serpent.
