SB 4.8.6

athatah kirtaye vamsam
punya-kirteh kurudvaha
svayambhuvasyapi manor
harer amsamsa-janmanah
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
Maitreya continued: O best of the Kuru dynasty, I shall now describe to you the descendants of Svayambhuva Manu, who was born of a part of a plenary expansion of the Supreme Personality of Godhead.
 
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
Lord Brahma is a powerful expansion of the Supreme Personality of Godhead. Although Brahma is jiva-tattva, he is empowered by the Lord, and therefore he is considered a plenary expansion of the Supreme Godhead. Sometimes it happens that when there is no suitable living being to be empowered to act as Brahma, the Supreme Lord Himself appears as Brahma. Brahma is the plenary expansion of the Supreme Personality of Godhead, and Svayambhuva Manu was the direct son of Brahma. The great sage Maitreya is now going to explain about the descendants of this Manu, all of whom are widely celebrated for their pious activities. Before speaking of these pious descendants, Maitreya has already described the descendants of impious activities, representing anger, envy, unpalatable speech, quarrel, fear and death. Purposely, therefore, he is next relating the history of the life of Dhruva Maharaja, the most pious king within this universe.
