itihÄsa - histories; purÄṇÄni - the PurÄṇas (supplementary Vedas); pañcamam - the fifth; vedam - the Vedic literature; īśvaraḥ - the Lord; sarvebhyaḥ - all together; eva - certainly; vaktrebhyaḥ - from his mouths; sasá¹›je - created; sarva - all around; darÅ›anaḥ - one who can see all time.
There are histories of particular countries and nations and of the world, but the PurÄṇas are the histories of the universe, not only in one millennium but in many kalpas. BrahmÄ has knowledge of those historical facts, and therefore all the PurÄṇas are histories. As originally composed by BrahmÄ, they are part of the Vedas and are called the fifth Veda.
