These, beholding as they do all the practices of one's life become one's witnesses. Days and Nights,--the former characterised by the virtue of displaying all things and the latter characterised by the virtue of concealing all things,--are running incessantly and touching all things (and thereby lessening their allotted periods of existence). Do thou, therefore, be observant of the duties of thy own order.[1727] The road in the other world (that leads to the regions of Yama), is infested by many foes (in the form of iron-beaked birds and wolves) and by many repulsive and terrible insects and worms. Do thou take care of thy own acts, for only acts will accompany you along that road. These one has not to share one's acts with others, but every one enjoys or endures the fruits of those acts which every one has himself performed. As Apsaras and great Rishis attain to fruits of great felicity, after the same manner, men of righteous deeds, as the fruits of their respective righteous acts, obtain in the other world cars of transcendent brightness that move everywhere at the will of the riders. Men of stainless deeds and cleansed souls and pure birth obtain in the next world fruits that correspond with their own righteous acts in this life. By walking along the high road constituted by the duties of domesticity, men acquire happy ends by attaining to the region of Prajapati or Vrihaspati or of him of a hundred sacrifices. I can give thee thousands and thousands of instructions. Know, however, that the puissant cleanser (viz., Righteousness), keeps all foolish persons in the Dark.[1728] Thou hast passed four and twenty years. Thou art now full five and twenty years of age. Thy years are passing away. Do thou begin to lay thy store of righteousness. The Destroyer that dwells within error and heedlessness will very soon deprive thy senses of their respective powers. Do thou before that consummation is brought about, hasten to observe thy duties, relying on thy body alone.
