They are not, they cannot go by the air speed. They fly on the air, but not with the air speed. So in this way, still, avicintya-tattve, after going many, many millions of years in that speed, still you will find, "Oh, Goloka Vṛndāvana is far, far away." This is the position.
So that Krsna... And we are explaining what is Kṛṣṇa. Don't consider Kṛṣṇa is ordinary human being. Avajānanti māṁ mūḍhā mānuṣīṁ tanum āśritam (BG 9.11). Because He kindly appears before us just like ordinary human being, don't think that He is like us. It is the conclusion. Just like these rascals, they think that "Because Kṛṣṇa appeared as a human being, I am also God. I am also God. Why Kṛṣṇa shall be alone God?" So we are trying to explain what is Kṛṣṇa, Hṛṣīkeśa. Hṛṣīkeśa. Then goloka-nāmni. Goloka eva nivasaty akhilātma-bhūtaḥ. Goloka eva nivasati.
