SB 5.1.4
samsayo ’yam mahan brahman
daragara-sutadisu
saktasya yat siddhir abhut
krsne ca matir acyuta
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
The King continued: O great brahmana, this is my great doubt. How was it possible for a person like King Priyavrata, who was so attached to wife, children and home, to achieve the topmost infallible perfection in Krsna consciousness?
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
King Pariksit wondered how a person so attached to wife, children and home could become so perfectly Krsna conscious. Prahlada Maharaja has said:
matir na krsne paratah svato va
mitho ’bhipadyeta grha-vratanam
A grhavrata, one who has taken a vow to execute family duties, has no chance to become Krsna conscious. This is because most grhavratas are guided by sense gratification and therefore gradually glide down to the darkest regions of material existence (adanta-gobhir visatam tamisram). How can they possibly become perfect in Krsna consciousness? Maharaja Pariksit asked Sukadeva Gosvami to resolve this great doubt.
