Why you should interpret? It is a fact that Brahmā's āyuḥ, his duration of life, is very, very big. Not only Brahmā's āyuḥ, even if you go higher planetary system . . . you are going to the moon planet. There are living entities. I do not know why they say there is no living being. Where they are going? But if we believe our śāstra, the moon planet is one of the heavenly planets, and the duration of life in the moon planet is ten thousands of years. And their year means our six months equal to their one day. That is called divya. In this way that high . . . not only . . . as you go more and more to the higher planetary system, you become more and more opulent. Just like here in this material world also, if you go Europe, America, you become more opulent automatically. Automatically. I am giving some example. Similarly, if you can go to the heavenly planet, you become more opulent.
Therefore they are aspiring after going to the higher planetary system. Karma-kāṇḍīya. They perform yajñas and pious activities to go to the heavenly planets. Oh, what is the idea? The idea is that we shall be able to enjoy more, more, more duration of life, more opulence, more money, more beautiful woman, more nice garden. Actually, that is a fact. That is a fact. But a devotee is not interested in all these things. A devotee is not interested because he accepts Kṛṣṇa. Therefore he is not interested. Kṛṣṇa says, ābrahma-bhuvanāl lokāḥ punar āvartino 'rjuna (BG 8.16): "My dear Arjuna, even if you are promoted to the Brahmaloka, or the planet where Brahmā lives, where the duration of life already I have explained, and opulence, and very, very great powerful, but still you have to fall down from there."
So why a devotee should be interested in such thing? No. A devotee wants Kṛṣṇa, the supreme eternal. Nityo nityānāṁ cetanaś cetanānām (Kaṭha Upaniṣad 2.2.13). That is the Vedic version. The Supreme Lord is the supreme leader of the nityas. We are all nityas, eternal. He guides. Therefore Kṛṣṇa plays with the living entities, Nārāyaṇa, Kṛṣṇa, in the spiritual world. There Kṛṣṇa and the devotees become His friend, cowherd boy. They play with Kṛṣṇa. They want that thing.
