Apatya means we are expanding. We are single—now we are expanding, expanding by our children, apatya.
And dāra means wife. The Sanskrit word strī . . . strī means woman, and the root meaning of strī means "which expands." As soon as you have got wife, you expand yourself. You are one, and as soon as you get your wife, you become three, four, five. So strī means that helps me expanding. That is the root meaning.
So Prahlāda Mahārāja says that what is the use by expanding your attachment to this material world by children? Apatya-dāra. Dārāgāra. Dāra means wife, and āgāra means house. Dārāgāra-dhanadayaḥ. Dhanādayaḥ means riches. These are our expanding processes.
And rājya, kingdom. Rājya. Kośa. Kośa means treasury. These are concerned with government. Government wants to expand. Rājya, kośa, and gaja. Gaja means elephant. The royal orders, they keep elephants. Especially in India, those who are princely order, they must keep at least dozens of elephants, and many thousands of horses.
That is royal opulence. So rājya-kośa-gajāmātya (SB 7.7.44). Amātya means minister, and bhṛtya, bhṛtya means servants, and āptā mean friend. That means, in other words, Prahlāda Mahārāja says that there is no necessity of expanding these material opulences.
