These people are trying to know the moon planet, the Venus planet or other planets. They're going, ascending, by aeroplane, and to know it. But they're doing it for the last twenty years. They do not know what is the actual position of the moon planet. That is not known. They're coming, going. Or whether they have gone, that they know. But from the situation it is understood they're not going. Maybe some other planet they are going. That is my opinion.
Because the description of the moon planet does not tally. We have got in the Śrīmad-Bhāgavatam . . . the, this moon planet is one of the heavenly planets. There, very high class of demigods, they live. Or one who is elevated to the moon planet, he is living there for ten thousands of years. Ten . . . what kind of ten thousands of years? In the moon planet, one day equal to our six months. Such months' year, and ten thousands of years. That is the duration of life in the moon planet. Those who are karma-kāṇḍīya, perform ritualistic ceremonies very nicely, they are promoted to the moon planet. And there are other planets also. This, Svargaloka. There are seven planetary system upwards, and seven planetary system downwards. Now we are living in the Bhūrloka, middle. Then above this, there is Bhuvarloka. Above this, there is Svarloka. Above this is Janaloka, Maharloka, Tapoloka, Brahmaloka. So this āroha . . . you cannot go to the Brahmaloka, although there is śāstra . . . or you cannot go to the sun planet also. You are seeing every day, but go there . . . but you have no right. You cannot go.
