TRANSLATION
By His own potency, the Supreme Personality of Godhead, who has multifarious potencies, appeared in the form of a dwarf as Urukrama, the twelfth son of Aditi. In the womb of His wife, whose name was Kīrti, He begot one son, named Bṛhatśloka, who had many sons, headed by Saubhaga.
PURPORT
As the Lord says in  Bhagavad-gītā  (4.6):
ajo 'pi sann avyayātmā bhūtānām īśvaro 'pi san prakṛtim svām adhiṣṭhāya sambhavāmy ātma-māyayā
“Although I am unborn and My transcendental body never deteriorates, and although I am the Lord of all sentient beings, I still appear in every millennium in My original transcendental form.” When the Supreme Personality of Godhead incarnates, He does not need any help from the external energy, for He appears as He is by His own potency. The spiritual potency is also called  māyā . It is said,  ato māyāmayam viṣṇum pravadanti manīṣiṇaḥ : the body accepted by the Supreme Personality of Godhead is called  māyāmaya . This does not mean that He is formed of the external energy; this  māyā  refers to His internal potency.
