So here it is said, kṣudrāyuṣām: "those who have got small duration of life." Although this small duration of life, human life, in comparison to the duration of life of other planets, it is very, very small, so but they do not know how to fulfill the mission of living condition during this life. In the animal life, the consciousness is not developed, but in the human form of life, although it is perishable, adhruvam... Prahlāda Mahārāja said, adhruvam. Dhruva. Dhruva means certain. So he advised,
- kaumāra ācaret prājño
- dharmān bhāgavatān iha
- durlabhaṁ mānuṣaṁ janma
- tad apy adhruvam arthadam
- (SB 7.6.1)
That is his advice, Prahlāda Mahārāja. He was talking with his classfriend, five years old. So he was teaching them that "Just become Kṛṣṇa conscious. Chant Hare Kṛṣṇa." Nārada taught him. He listened from Nārada. So he was convinced that this is the only business, how to make advancement in Kṛṣṇa consciousness by chanting Hare Kṛṣṇa mantra.
