The post of Lord BrahmÄ is meant for very highly elevated, spiritually advanced living beings. When such living beings are unavailable, Lord Viá¹£á¹u, the Supreme Personality of Godhead, expands Himself as Lord BrahmÄ. This takes place very rarely. Consequently there are two kinds of BrahmÄs. Sometimes BrahmÄ is an ordinary living entity, and at other times BrahmÄ is the Supreme Personality of Godhead. The BrahmÄ spoken of here is an ordinary living being. Whether BrahmÄ is the Supreme Personality of Godhead or an ordinary living being, he is known as VairÄja BrahmÄ and Hiraá¹yagarbha BrahmÄ. Therefore the sun-god is also accepted as VairÄja BrahmÄ.
