Those born into royalty can use it to remember their Krishna-Consciousness and attain liberation.

Now what actually happens to the unsuccessful spiritualist? Śrī Kṛṣṇa specifically explains,

prāpya puṇya-kṛtāṁ lokān
uṣitvā śāśvatīḥ samāḥ
śucīnāṁ śrīmatāṁ gehe
yoga-bhraṣṭo ’bhijāyate

athavā yoginām eva
kule bhavati dhīmatām
etad dhi durlabhataraṁ
loke janma yad īdṛśam

“The unsuccessful yogī, after many, many years of enjoyment on the planets of the pious living entities, is born into a family of righteous people, or into a family of rich aristocracy. Or he takes his birth in a family of transcendentalists who are surely great in wisdom. Verily, such a birth is rare in this world.” (Bg. 6.41–42)

Kṛṣṇa further indicates that of all good families to be born into – families of successful merchants or philosophers or meditators – the best is the family of yogīs. One who takes birth in a very rich family may be misled. It is normal for a man who is given great riches to try to enjoy those riches; thus rich men’s sons often become drunkards or prostitute hunters. Similarly, one who takes birth in a pious family or in a brahminical family often becomes very puffed up and proud, thinking, “I am a brāhmaṇa; I am a pious man.” There is chance of degradation in both rich and pious families, but one who takes birth in a family of yogīs or of devotees has a much better chance of cultivating again that spiritual life from which he has fallen. Kṛṣṇa tells Arjuna,

tatra taṁ buddhi-saṁyogaṁ
labhate paurva-dehikam
yatate ca tato bhūyaḥ
saṁsiddhau kuru-nandana

“On taking such a birth, he again revives the divine consciousness of his previous life, and he tries to make further progress in order to achieve complete success, O son of Kuru.” (Bg. 6.43)

Being born in a family of those who execute yoga or devotional service, one remembers his spiritual activities executed in his previous life. Anyone who takes to Kṛṣṇa consciousness seriously is not an ordinary person; he must have taken to the same process in his previous life. Why is this?

pūrvābhyāsena tenaiva
hriyate hy avaśo ’pi saḥ

“By virtue of the divine consciousness of his previous life, he automatically becomes attracted to the yogic principles – even without seeking them.” (Bg. 6.44)
