Study Bhagavad-gītā to understand the real nature or identification of God and yourself and your relationship, and then, when you are little conversant, when you are prepared that "Yes, Kṛṣṇa is the only lovable object," then next book you take, Śrīmad-Bhāgavatam. And you go on.
Just like Bhagavad-gītā As It Is is entrance. Just like students, they pass their school examination then enters into the college. So you pass your school examination, how to love God, by studying Bhagavad-gītā As It Is. Then study Śrīmad-Bhāgavatam, and . . . that is graduate study. And when you are still farther advanced, postgraduate, then study Teachings of Lord Caitanya.
So there is no difficulty. The fact is that we have to learn how to love Kṛṣṇa. So direction is there and method is there, and we are trying to serve you as far as possible. We are sending our boys in the streets and the town to invite you. And if you kindly take up this opportunity, then your life will be successful. Premā pum-artho mahān (Śrīnātha Cakravartī's commentary on Śrīmad-Bhāgavatam).
Because this human form of life is meant for developing love for God. Because in all other life we have learned . . . we have loved. We have loved our children, we have loved our wife, we have loved our nest in the bird's life, in the beast's life. There is love. There is no necessity of teaching a bird or beast how to love the children. There is no necessity, because that is natural.
