PURPORT

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