, the Supreme or Purusha and his Maya and Jiva and Avidya or Ignorance) be the cause, they that are conversant with Adhyatma behold Prakriti as the cause of all creatures. That Prakriti which is Unmanifest, becomes manifest in the form of these principles. Myself, thyself, O monarch, and all others that are endued with body are the result of that Prakriti (so far as our bodies are concerned). Insemination and other (embryonic) conditions are due to the mixture of the vital seed and blood. In consequence of insemination the result which first appears is called by the name of "Kalala." From "Kalala" arises what is called "Vudvuda" (bubble). From the stage called "Vudvuda" springs what is called "Pesi." From the condition called "Pesi" that stage arises in which the various limbs become manifested. From this last condition appear nails and hair. Upon the expiration of the ninth month, O king of Mithila, the creature takes its birth so that, its sex being known, it comes to be called a boy or girl. When the creature issues out of the womb, the form it presents is such that its nails and fingers seem to be of the hue of burnished copper. The next stage is said to be infancy, when the form that was seen at the time of birth becomes changed. From infancy youth is reached, and from youth, old age. As the creature advances from one stage into another, the form presented in the previous stage becomes changed. The constituent elements of the body, which serve diverse functions in the general economy, undergo change every moment in every creature. Those changes, however, are so minute that they cannot be noticed.[1700] The birth of particles, and their death, in each successive condition, can not be marked, O king, even as one cannot mark the changes in the flame of a burning lamp.
