However intelligent we may be, however proud we may be for our possession, but the death is sure. "As sure as death." And when death comes—the death is also another form of Kṛṣṇa—then He will take everything.
Just like Hiraṇyakaśipu. He was very, very proud of his possession. He was controlling over the three worlds. He was chastising his Vaiṣṇava son, Prahlāda Mahārāja. In this way he was very, very proud. But when Kṛṣṇa came as Nṛsiṁhadeva, everything was finished within a second. So we should not mistake this, I mean to say, fact.
Kṛṣṇa therefore presents that "Your real problem is birth, death, old age, and disease, your real problem. You are making solution of all the problems by scientific advancement, by education, by so on, so on, political maneuver, everything. It is all right, but how you are going to solve this problem—janma-mṛtyu-jarā-vyādhi-duḥkha-doṣānudarśanam (BG 13.9)? How you'll solve this problem?" Actually human life is meant for solving this problem, not this temporary problem. Temporary problem will go on. If you don't solve this problem, janma-mṛtyu-jarā-vyādhi, then any form of life, there will be problems. Even if you are elevated to the heavenly planets, there are also problems. Indra is not very happy there, the king of heavenly planet. Although the higher planets, the duration of life, the standard of civilization, standard of comforts many, many thousand times greater than here, but the same problem—janma-mṛtyu-jarā-vyādhi—is there. You cannot avoid it.
