Mbh 5.123.1b

Thou knowest, O holy one, that the regions created for me were all eternal. Why were all those regions of mine destroyed, O thou of great effulgence?” The Grandsire answered, saying, “Thy merit, augmented by a (virtuous) rule over thy subjects for many thousands of years and won by innumerable sacrifices and gifts, was exhausted by only one fault, in consequence of which thou wert hurled (from this region). That fault, O king of kings, was thy vanity for which thou hadst become an object of contempt with all the residents of heaven. O royal sage, this region can never be rendered eternal by vanity, or pride of strength, or malice, or deceitfulness, or deception. Never disregard those that are inferior, or superior, or in the middle station. There is not a greater sinner than he who is consumed by the fire of vanity. Those men that will converse upon this fall and re-ascension of thine, will, without doubt, be protected even if overtaken by calamity.”’
