Rocket, yes. But then, going with great force, but āruhya kṛcchreṇa . . . similarly, one can rise up to the Brahman effulgence, but if there is no shelter . . . just like these people are going, but they don't get any shelter. But they come down again. Similarly, one, by severe austerities and penances, may go up to the Brahmaloka, but he has no position. He has no position. Because in the Brahmaloka or Vaikuṇṭhaloka, in the Paravyoma, the spiritual sky, there are spiritual planets. They are called Vaikuṇṭhaloka. Hundreds and millions there are. Very, very big, big planets than these material planets. So unless you get a shelter in one of the planets, then you again fall down.
So that is . . . because we are after ānanda, sac-cid-ānanda. Simply to rise to the platform of Brahman, that is sat, partial realization of the Absolute Truth. Sat. Then cit. Cit means knowledge. That is also partial. Ānanda. Sac-cid-ānanda. When there . . . ānanda you cannot get. Just like if you, simply in the sky you fly, you don't get ānanda. Therefore you have come to down, come down again to the airplane, airport. Without that, there is no ānanda. Similarly, simply rising up to the Brahman effulgence, there is no ānanda. Ānanda means you have to enter into the spiritual planet, where Nārāyaṇa, Kṛṣṇa, is there.
