Different creatures have been created with different ends. Some are intended for the path of Pravritti and some for that of Nivritti. According to the path that a creature follows is the reward that he enjoys. This Brahman is the master of all the worlds. Endued with puissance it is he that creates the universe. He is your mother and father, and he is your grandfather. At my command, he will be the giver of boons unto all creatures. His son Rudra, who has sprung from his brow at his command, will, endued with puissance, uphold all created beings. Go ye to your respective jurisdictions, and seek, according to the ordinances, the good of the worlds. Let all the scriptural acts flow in all the worlds. Let there be no delay in this. Ye foremost of celestials, do ye ordain the acts of all creatures and the ends that they are to attain therefore. Do ye appoint also the limits of the periods for which all creatures are to live. This present epoch that has been set to run is the foremost of all epochs and should be known by the name of Krita. In this Yuga living creatures should not be slain in the sacrifices that may be performed. It should be as I ordain and let it not be otherwise. In this age, ye celestials, Righteousness will flourish in its entirety. After this age will come the epoch called Treta. The Vedas, in that Yuga, will lose one quarter. Only three of them will exist.
