by indulgence in sensuality and similar demoralising practices it is born in the lower species of animals, and by sinful acts, it goes to the infernal regions. Afflicted with the miseries of birth and dotage, man is fated to rot here below from the evil consequences of his own actions. Passing through thousands of births as also the infernal regions, our spirits wander about, secured by the fetters of their own karma. Animate beings become miserable in the next world on account of these actions done by themselves and from the reaction of those miseries, they assume lower births and then they accumulate a new series of actions, and they consequently suffer misery over again, like sickly men partaking of unwholesome food; and although they are thus afflicted, they consider themselves to be happy and at ease and consequently their fetters are not loosened and new karma arises; and suffering from diverse miseries they turn about in this world like a wheel. If casting off their fetters they purify themselves by their actions and practise austerities and religious meditations, then, O best of Brahmanas, they attain the Elysian regions by these numerous acts and by casting off their fetters and by the purification of karma, men attain those blissful regions where misery is unknown to those who go there. The sinful man who is addicted to vices, never comes to the end of his course of iniquities.
