For forever, millions of years, if you speculate, to understand what is God, it is not possible. It is not a subject matter of speculative knowledge. No. It is to be received through the right source, deductive process, not inductive process. Because our senses are limited. We cannot have any perfect idea on account of our senses being limited. We cannot see.
So there are so many examples. We have talked. This knowledge is not... The exact word used in Sanskrit... There are two ways: āroha-panthā, avaroha-panthā. Āroha-panthā means to know something by your dint of knowledge, ascending process, ascending process. Just like these people are trying to know the moon planet, the Venus planet, or other planets. They're going, ascending by airplane. 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, 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 is Svargaloka.
