SB 1.3.6

sa eva prathamaṁ devaḥ
 kaumāraṁ sargam āśritaḥ
cacāra duścaraṁ brahmā
 brahmacaryam akhaṇḍitam

Translation: 

First of all, in the beginning of creation, there were the four unmarried sons of Brahmā [the Kumāras], who, being situated in a vow of celibacy, underwent severe austerities for realization of the Absolute Truth.

Purport: 

The creation of the material world is effected, maintained and then again annihilated at certain intervals. So there are different names of the creations in terms of the particular types of Brahmā, the father of the living beings in the creation. The Kumāras, as above mentioned, appeared in the Kaumāra creation of the material world, and to teach us the process of Brahman realization, they underwent a severe type of disciplinary action as bachelors. These Kumāras are empowered incarnations. And before executing the severe type of disciplinary actions, all of them became qualified brāhmaṇas. This example suggests that one must first acquire the qualifications of a brāhmaṇa,not simply by birth but also by quality, and then one can undergo the process of Brahman realization.

SB 1.3.7

dvitīyaṁ tu bhavāyāsya
 rasātala-gatāṁ mahīm
uddhariṣyann upādatta
 yajñeśaḥ saukaraṁ vapuḥ

Translation: 

The supreme enjoyer of all sacrifices accepted the incarnation of a boar [the second incarnation], and for the welfare of the earth He lifted the earth from the nether regions of the universe.

Purport: 

The indication is that for each and every incarnation of the Personality of Godhead, the particular function executed is also mentioned. There cannot be any incarnation without a particular function, and such functions are always extraordinary. They are impossible for any living being to perform. The incarnation of the boar was to take the earth out of Pluto’s region of filthy matter. Picking up something from a filthy place is done by a boar, and the all-powerful Personality of Godhead displayed this wonder to the asuras, who had hidden the earth in such a filthy place. There is nothing impossible for the Personality of Godhead, and although He played the part of a boar, by the devotees He is worshiped, staying always in transcendence.
