Atheists cannot understand the purpose behind the creation. Although this material world is condemned when it is compared to the spiritual world, there is still some purpose behind it. Modern scientists and philosophers cannot understand that purpose, nor do they believe in the existence of a creator. They try to establish everything by their so-called scientific research, but they do not center anything around the supreme creator.

As a householder, Pṛthu Mahārāja had five sons by his wife, Arci, and all these sons were begotten as he desired them. They were not born whimsically or by accident. How one can beget children according to one’s own desire is practically unknown in the present age, Kali-yuga.

Sometimes the sun shines on stool, urine and so many other polluted things, but since the sun is all-powerful, it is never affected by the polluted things with which it associates. On the contrary, the sunshine sterilizes and purifies polluted and dirty places. Similarly, a devotee may engage in so many material activities, but because he has no desire for sense gratification, they never affect him. On the contrary, he dovetails all material activities for the service of the Lord.

A soul dedicated to the service of the Lord should never think of himself as the personal proprietor or the superintendent. A dedicated devotee should prosecute his work according to the rules and regulations described in devotional service. The results of his activities are completely dependent on the supreme will of the Lord.

Śrīla Rūpa Gosvāmī has advised that things which are favorable to devotional service should not be rejected, nor should activity favorable for devotional service be considered ordinary work or fruitive activity. For example, an ordinary worker conducts business in order to earn money for his sense gratification. A devotee may perform the same work in exactly the same way, but his aim is to satisfy the Supreme Lord. Consequently his activities are not ordinary.

Remaining fixed in devotional service gives one the utmost in self-satisfaction. Actually self-satisfaction can be achieved only by pure devotees, who have no desire other than to serve the Supreme Personality of Godhead. Since the Supreme Personality of Godhead has nothing to desire, He is fully satisfied with Himself. Similarly, a devotee who has no desire other than to serve the Supreme Personality of Godhead is as self-satisfied as the Supreme Lord.

Like the great sage Nārada, the Kumāras do not require any machine to travel in space. There are also residents of Siddhaloka who can travel in space without machines. Since they can go from one planet to another, they are called siddhas — that is to say, they have acquired all mystic and yogic powers.

Knowledge of Kṛṣṇa is such a great gift that it is impossible to repay the benefactor. Therefore Pṛthu Mahārāja requested the Kumāras to be satisfied by their own benevolent activities in delivering souls from the clutches of māyā. The King saw that there was no other way to satisfy them for their exalted activities.

Everything belongs to the brāhmaṇas, but the kṣatriya government and the mercantile people keep everything in custody, like bankers, and whenever the brāhmaṇas need money, the kṣatriyas and vaiśyas should supply it. It is like a savings account with money which the depositor can draw out at his will. The brāhmaṇas, being engaged in the service of the Lord, have very little time to handle the finances of the world, and therefore the riches are kept by the kṣatriyas, or the kings, who are to produce money upon the brāhmaṇas’ demand.

When monarchy ruled throughout the world, the monarch was actually directed by a board of brāhmaṇas and saintly persons. The king, as the administrator of the state, executed his duties as a servant of the brāhmaṇas. It was not that the kings or brāhmaṇas were dictators, nor did they consider themselves proprietors of the state.
