Haṁsadūta: Now, if someone is married, gṛhastha, under the varṇāśrama-dharma, is it the duty of gṛhasthas to have children? Are there some qualifications of gṛhasthas, that gṛhasthas, they're required, like they are required to support the brāhmaṇas, like that?
Prabhupāda: Gṛhastha? Gṛhastha means to live with wife. This is the meaning of gṛhastha. And a gṛhastha is supposed to support others who are not gṛhasthas just like brahmacārī. Brahmacārī means student life. So gṛhasthas support them. (break) ...sannyāsīs, other three classes. Because they are engaged in a different subject matter, they have no time to earn their livelihood, and therefore, those who are gṛhasthas, they take charge of him. This is the Vedic system. But they should live also on the bare necessities of life. They should not be luxurious. A brahmacārī cannot be luxurious. A sannyāsī cannot be luxurious. A vānaprastha cannot be luxurious. Luxury is allowed only to the householder because they are earning their own money. Others are dependent. So one cannot be luxurious at the expense of others. That is not allowed.
