In the chapter dealing with Ganesha and his mount we have noticed how Agni one of the twenty-five principles of the philosophy of Sankya became a mouse and how it was given to Ganesha who used it as his mount. As the Sankya system of thought formed the basis of all Yoga systems in the subsequent periods we have to understand the correct import of these twenty-five principles. The Sankya philosophy is mainly metaphysical and psychological in its scope and any interpretation which is inconsistent with this scope is bound to mislead us. Among the twenty-five principles there is no difficulty in understanding twenty principles. But five, viz., (1) Vak said to be the mouth, (2) Pani said to be hands (3) Padam said to be the legs (4) Payu said to be the anus and (5) Upastham said to be the genitals are confusing. In the human body, the torso and the head are the most important parts. There are persons falling under the category of neuter gender. Obviously such persons cannot come under the category said to be envisaged by sankya. More over the mouth and anus are only two openings of one and the same organ the alimentary canal, the mouth being the opening into the organ and the anus being the opening out from the organ. The functions of these several organs are more physical than metaphysical, which the sankya system is.
