I'll give you one practical example. In my householder life I was a drugstore businessman. So one Muhammadan gentleman, he was supplying me bottles. So by doing this bottle business he accumulated some money. So one day I asked this old man—his name was Abdula—"Well, Mr. Abdula, you have got some now money, I can understand. So how you are going to use it?" So he said: "My dear sir, I am thinking of constructing a mosque." He was Muhammadan. Just see his mentality, that he wanted . . . he accumulated some money, but now he wants to satisfy God, constructing a big temple or constructing . . .
You'll find in India some old temples, there are so many nice workmanship in stone. That means spent thousands and thousands of dollars. In here also I find so many nice churches, they have been spent by persons. What is the idea? The idea is anyone who has got some money, he wanted to satisfy God. So it doesn't matter what you are doing, but the test of your success will be considered as successful if you try to satisfy God.
Because we are, whole life, we are dragging from God, "God, give us our daily bread," and God is supplying daily bread. Otherwise, where you are getting bread? You say: "I am purchasing from the market." Oh, where the storekeeper got this wheat? It is produced by agriculture. But do you think that simply by machine it is produced? No. Unless there is some natural favorable condition, you cannot produce.
There are five causes—the land, labor, capital, organization, and Bhagavad-gītā accepts daiva, another cause. Daiva means godly. You may arrange everything, but if God is against you, in spite of your all arrangement, everything will be failure. That is described in the Bhagavad-gītā. They have searched out five causes for successful. So out of the five causes, daiva—daiva means the favor of God—that has been taken as the means for any successful thing.
So Prahlāda Mahārāja is teaching to his class friends that, "My dear friends, you try to understand this bhāgavata-dharma." What is bhāgavata-dharma? This is Sanskrit word. Bhāgavata means pertaining to God. Bhagavān means God, and bhāgavata, pertaining to God, that is called bhāgavata. So bhāgavata-dharma means . . . the purpose of bhāgavata-dharma means pertaining to my . . . you have to test the success of your activities by pleasing God. That is bhāgavata-dharma.
Just like in your office you want to satisfy your boss. In your school or college you want to satisfy your teacher or principal. Similarly, the supreme teacher, the supreme boss, is the Supreme Personality of Godhead. So saṁsiddhir hari-toṣaṇam (SB 1.2.13). This is the sum and substance of bhāgavata-dharma, that one has to test the success of his activities. It doesn't matter what it is.
