Governed by my ordinance, men wander within my body, their senses overwhelmed by me.  They move not according to their will but as they are moved by me.  Regenerate Brahmanas that have thoroughly studied the Vedas, that have tranquillity in their souls, they that have subdued their wrath, obtain a high reward by means of their numerous sacrifices.  That reward, however, is unattainable by men that are wicked in their deeds, overwhelmed by covetousness, mean and disreputable with souls unblessed and impure.  Therefore, must thou know, O Brahmana that this reward which is obtained by persons having their souls under control and which is unobtainable by the ignorant and the foolish,—­this which is attainable by asceticism alone,—­is productive of high merit.  And, O best of men, at those times when virtue and morality decrease and sin and immorality increase, I create myself in new forms.  And, O Muni, when fierce and malicious Daityas and Rakshasas that are incapable of being slain by even the foremost of the gods, are born on earth, I then take my birth in the families of virtuous men, and assuming human body restore tranquillity by exterminating all evils.  Moved by my own maya, I create gods and men, and Gandharvas and Rakshasas, and all immobile things and then destroy them all myself (when the time cometh).  For the preservation of rectitude and morality I assume a human form, and when the season for action cometh, I again assume forms that are inconceivable.  In the Krita age I become white, in the Treta age I become yellow, in the Dwapara I have become red and in the Kali age I become dark in hue, I the Kali age, the proportion of immorality becometh three-fourths, (a fourth only being that of morality).  And when the end of the Yuga cometh, assuming the fierce form of Death, alone I destroy all the three worlds with their mobile and immobile existences.  With three steps, I cover the whole Universe; I am the Soul of the universe; I am the source of all happiness; I am the humbler of all pride; I am omnipresent; I am infinite; I am the Lord of the senses; and my prowess is great.  O Brahmana, alone do I set a-going the wheel of Time; I am formless; I am the Destroyer of all creatures; and I am the cause of all efforts of all my creatures.  O best of Munis, my soul completely pervadeth all my creatures, but, O foremost of all regenerate ones, no one knoweth me.  It is me that the pious and the devoted worship in all the worlds.  O regenerate one, whatever of pain thou hast felt within my stomach, know, O sinless one, that all that is for thy happiness and good fortune.  And whatever of mobile and immobile objects thou hast seen in the world, everything hath been ordained by my Soul which is the Spring of all existence.  The grandsire of all creatures is half my body; I am called Narayana, and I am bearer of the conch-shell, the discus and the mace.  O regenerate Rishi, for a period measured by a thousand times the length of the Yugas, I who am the Universal
