To understand religion on the basis of philosophy and logic, not blindly accepting. So this is called bhāgavata-dharma.
So Prahlāda Mahārāja recommends that from childhood this should be instructed. Because nobody is caring to teach this science of God from childhood. Therefore the present population, godless population, is the cause of all disturbances. In the Bhagavad-gītā you'll find varṇa-saṅkara. Varṇa-saṅkara means population, unwanted population.
What is the use of this population? Simply for living? The Bhāgavata says does the tree not live? The tree also lives for thousands of years. So do you mean to say living is very important thing? No. There are many trees they are living for thousands of years. So what is the value of living?
If you say: "Oh, the tree lives, but it cannot breathe." Breathing. The Bhāgavata says the bellow, it breathes very nicely. "Well, the bellow can breathe, but it cannot eat." "Oh, the dogs and hogs, they do not eat?" There are so many questions and answers in the Bhāgavata. But actually, population, important population, means who are conversant with the science of God.
