Here, this is your self (atman) that is within all.

Which one is the one within all, Oh Yajnavalkya?

That which transcends all hunger and thirst, grief, delusion, decay of age, and death. [Yajnavalkya continues—]

It is that self ( atman) knowing which the Brahmanas (children of Brahman) rise above the desire for progeny, desire for wealth and comfort, the desire for repute and honour, and wander depending on alms.

What the desire for progeny is that very one is the desire for wealth and comfort. What the desire for wealth and comfort is that very one is the desire for repute and fame. They are all the same desires.

Therefore a Brahmana (child of Transcendental God) should become disinterested in scholarliness and should desire to stay in a state of childhood.

Becoming disinterested in childhood or scholarliness, he should become a contemplative silent sage (muni).

Becoming disinterested in silence and non-silence, contemplation and non-contemplation, he should become a child of Brahman.

By what means shall he become a child of Brahman?

By whatever means he shall become a child of Brahman, let him be thus alone.

All else is torment and grief.

Then Kahola Kaushitakeya fell silent and withdrew.
