In this material world the auspicious and inauspicious are simply mental concoctions because such things exist only due to association with the material world. This is called illusion, or atma-maya. We think ourselves created by material nature exactly as we think ourselves experiencing so many things in a dream. The spirit soul, however, is always transcendental. There is no question of becoming materially covered. This covering is simply something like a hallucination or a dream. In Bhagavad-gita (2.62) it is also said, sangat sanjayate kamah. Simply by association we create artificial material necessities. Dhyayato visayan pumsah sangas tesupajayate. When we forget our real constitutional position and wish to enjoy the material resources, our material desires manifest, and we associate with varieties of material enjoyment. As soon as the concoctions of material enjoyment are there, because of our association we create a sort of lust or eagerness to enjoy them, and when that false enjoyment does not actually make us happy, we create another illusion, known as anger, and by the manifestation of anger, the illusion becomes stronger. When we are illusioned in this way, forgetfulness of our relationship with Krsna follows, and by thus losing Krsna consciousness, our real intelligence is defeated. In this way we become entangled in this material world. In Bhagavad-gita (2.63) it is said:

By material association we lose our spiritual consciousness; consequently there is the question of the auspicious and inauspicious. But those who are atmarama, or self-realized, have transcended such questions. The atmaramas, or self-realized persons, gradually making further progress in spiritual bliss, come to the platform of association with the Supreme Personality of Godhead. That is the perfection of life. In the beginning, the Kumaras were self-realized impersonalists, but gradually they became attracted to the personal pastimes of the Supreme Lord. The conclusion is that for those who are always engaged in the devotional service of the Personality of Godhead, the duality of the auspicious and inauspicious does not arise. Prthu Maharaja is therefore asking about auspiciousness not for the sake of the Kumaras but for his own sake.
