Now you can select your own religion. Either you be a Hindu or Muslim or Muhammadan or Buddhist—whatever you like—Śrīmad-Bhāgavata does not stop you, but it gives you hint what is the purpose of religion. The purpose of religion is to develop your love of Godhead. That is real religion. So here Kṛṣṇa says that yadā yadā hi dharmasya glānir bhavati (BG 4.7). As soon as there is decadence of people's love of Godhead . . . that means when people become forgetful, almost forgetful. Because at least some people remember that there is God. But generally, in this age, they are forgetful. That is dharmasya glāniḥ.
And by forgetting God the people cannot be happy. That is also another cause. People are thinking that, "God is dead," "We have no obligation to God," "There is no God." This sort of thinking will never make the people happy. And actually, it is happening. They have become atheistic. The modern civilization is godless, but people are not happy. Therefore God or His representative comes when people forget his relationship with God.
So real religion is to understand what is our relationship with God. And then the relationship is as it is found in the Bhagavad-gītā and confirmed by great ācāryas like Lord Caitanya. Lord Caitanya immediately enunciates the constitutional position of the living entity. Sanātana Gosvāmī inquired from Him that, "Who am I? Why I am always in miserable condition, three kinds of miserable condition?" So in answer to this question, "Who am I?" or "Who are these all these living entities?" Śrī Caitanya Mahāprabhu immediately answered that jīvera svarūpa haya nitya-kṛṣṇa-dāsa (CC Madhya 20.108): the real identity of the living entity is that he is eternally servant of God.
We should not understand this word servant in the meaning of materialistic servant. To become servant of God is a great position. That is not ordinary position. Just like people try to get some government servitorship, government service. That is also servant, to become servant. Why? Or people try to get some service in some established firm, well-reputed business firm. Why? That service is comfortable; there is great profit in such kind of service. So if people are satisfied by getting a government service or service in some good establishment, then just think over if you become servant of God then what is your position?
Because God is the government of all government. So to become servant of God . . . we are servant of God constitutionally. Just like Caitanya Mahāprabhu says, jīvera svarūpa haya nitya-kṛṣṇa-dāsa (CC Madhya 20.108).
