So bhakta means when we revive our relationship, how I am connected with Kṛṣṇa. Then he is bhakta. Then he is bhakta. That relationship is pervertedly reflected in this material world. That relationship. Somebody is related with Kṛṣṇa as master and servant. That is reflected here also. There is master and servant, but both of them are cheating one another. The master is trying to exploit the servant, and the servant is trying to exploit the master. They are also forming unions, how to exact money from the capitalists, and the capitalists trying to exploit this labor from the laborers. So here, that master and servant is there, but both of them are cheaters and cheated. That's all. But if we really want to be master and servant, the supreme master is Kṛṣṇa and you engage yourself in His service. You'll never be cheated. You'll never be cheated. You want to love. You love Kṛṣṇa as your husband or lover, you'll never be cheated. You love children. You love Kṛṣṇa as your child—just like Yaśodāmāyi accepted Kṛṣṇa as his child—you'll never be cheated. So the same relationship is there, but it is perverted reflection, and there is no happiness. But when we become bhakta or establish one's relationship with Kṛṣṇa... Just like Arjuna. Arjuna is bhakta. What kind of bhakta? Bhakto 'si me sakhā, sakhā ceti. "You are bhakta, at the same time My friend." So to become bhakta means either you become a friend of Kṛṣṇa or a servant of Kṛṣṇa or a lover of Kṛṣṇa or father of Kṛṣṇa or mother of Kṛṣṇa. In this way, there are so many. Or you become enemy of Kṛṣṇa. Just like Hiraṇyakaśipu.
So this is the process of understanding Bhagavad-gītā. Therefore I am speaking from this Fourth Chapter. The secret of understanding Bhagavad-gītā is here, and if you follow these principles... Just like when you purchase one bottle of medicine from the, I mean to say, drug shop, there is dose. Read, "This medicine is to be taken by this dose." If you follow the direction of the bottle label then you get benefit. Similarly, here is the direction: evaṁ paramparā-prāptam (BG 4.2). You have to understand Bhagavad-gītā from the disciplic succession, and that means one who is devotee, a devotee. Devotee. This disciplic succession devotee. Otherwise there is no possibility. If that disciplic succession is something else than devotional service, then he cannot understand Bhagavad-gītā. There are many practical experiences, and so many scholars, books we have studied, and their commentary is all nonsense because they are not bhakta. They try to understand Bhagavad-gītā simply by their academic qualification. That is not possible. That is not possible. If somebody is trying to Bhagavad-gītā by his academic qualification... What is the value of this academic qualification? It has no value in the presence of spiritual science. It is a different thing. It is to be understood in a different process.
So we shall discuss this Bhagavad-gītā, how Arjuna understood. If... This is a clear fact mentioned here, that before Arjuna, before meeting Arjuna, the science of Bhagavad-gītā was lost. It is clearly said. Sa kāleneha yogo naṣṭaḥ parantapa. That was lost. Although it is eternal, still, because the paramparā system or the disciplic succession broke, therefore the real meaning or real purport of Bhagavad-gītā was not received. It was broken. Naṣṭa means the paramparā system broken. Therefore Kṛṣṇa is appointing Arjuna to understand because he is devotee and friend. So if you accept Bhagavad-gītā as Arjuna understood it, then you are directly hearing from Kṛṣṇa. That is the process.
