We have to first of all establish our relationship with God. Your establish . . . is already established. Just like the father and the son—the relationship is already there. It is not . . . but still, sometimes the son goes out of home and may be forgetting his father. Similarly, we are out of home. We have come from the spiritual world in this material world. We have forgotten our father. So we have to revive this relationship with our father, or God, or Kṛṣṇa. That is the main business of human life. In other species of life lower than the human being it is not possible to revive our old relationship with God. But in this life . . . therefore this is the greatest opportunity. After all, we are under the grip of material nature's law. That is explained in there. Tathā dehāntara-prāptiḥ (BG 2.13). According to our desire, we are creating a different type of body, and after death, tathā dehāntara-prāptiḥ . . . just like the child is become a boy, the boy is becoming young man, the young man is becoming middle-aged man, and the middle-aged man is becoming old man. So what is next after the old body? The next is tathā dehāntara-prāptiḥ: you have to accept another body. This is called chain or cycle of birth and death, or transmigration of the soul. This is going on.
So if you want to . . . but nobody wants to die. Nobody wants to change this body. But this is a problem. One should know it. That is the first instruction given by Kṛṣṇa . . . (break) . . . Arjuna, that we are changing. Tathā dehāntara-prāptiḥ. So this is the opportunity, human life. If we want to stop this repetition of birth and death under different obligation and different circumstances, we should take instruction from Kṛṣṇa, try to understand Kṛṣṇa—that is Bhagavad-gītā—and make our life successful so that . . . understanding Kṛṣṇa means, as it is stated, tyaktvā dehaṁ punar janma naiti mām eti kaunteya (BG 4.9). We have come from God; we again go back to God if we simply understand Kṛṣṇa, or God. This is the whole instruction of the Bhagavad-gītā.
