Two Postures, One Animal, and the Habit of Pairing

Two animals in the classical corpus have a plain form and a stretched form: the tortoise and the frog. In both cases the second posture takes the first as its base and adds a movement of the upper body, and in both cases the compiler keeps the animal's name and qualifies it with uttana rather than inventing a new image.

That is a naming convention rather than a coincidence, and it tells us something about how the vocabulary was maintained. A compiler who wanted the list to be memorable had two ways to add an item: find a new resemblance, or mark a variation on one already established. Marking a variation costs the reader almost nothing, because the base posture is already in mind, and it keeps the pair together in the list where the relationship can be seen.

The Gheranda Samhita uses both methods, and its thirty two entries are the result: a wide bestiary of independent images, with two small pairs inside it where one shape opens into another. The atlas carries each as its own entry, following the text, and records the relationship in the prose. Mallinson and Singleton's Roots of Yoga gives the primary descriptions in translation, and reading the pairs consecutively is the easiest way to see the compiler's method working.
