Prahlāda Mahārāja said,
- kaumāra ācaret prājño
- dharmān bhāgavatān iha
- durlabhaṁ mānuṣaṁ janma
- tad apy adhruvam arthadam
- (SB 7.6.1)
He advises that from the very beginning of life, kaumāra... kaumāra means five years to ten years. This span of life is called kaumāra. Kaumāraṁ yauvanaṁ jarā, that as we are reading here, kaumāraṁ yauvanaṁ jarā. So kaumāra means boy's life. So kaumāra ācaret prājño dharmān bhāgavatān iha. A human being, he should learn about the Bhāgavata-dharma from the beginning of his kaumāra age, not that keep it aside, "When I shall become old man, then I shall read the scriptures." No. Kaumāra, from the boyhood. Kaumāra ācaret prājñaḥ. If one is actually having sense... Of course, a boy has no sense. It is the duty of the father and mother to engage the child, boy, from the beginning of his life in the matter of devotional service, bhāgavatān. Fortunately, we got a very nice father; he engaged us in this devotional service from the very beginning of our life. So it is the duty of every father, every state, every guru, every friend, every relative how to engage the boy in spiritual life.
