Śāstra says, tarko apratiṣṭhaḥ (CC Madhya 17.186). Simply by argument and reasoning, you cannot make any spiritual advancement. Because you may be very good, I mean to say, logician, putting forward nice arguments, but somebody may come who is better than you. He will spoil all your logic, and he will establish his own logic. That is nyāya-śāstra. In Sanskrit there is nyāya-śāstra. So they are taught how to defeat his opponent.
Therefore the Absolute Truth you cannot understand by argument, by material dealings. In the Brahma-saṁhitā it is said:
- panthās tu koṭi-śata-vatsara-sampragamyo
- vāyor athāpi manaso muni-puṅgavānām
- so 'py asti yat-prapada-sīmny avicintya-tattve
- govindam ādi-puruṣaṁ tam ahaṁ bhajāmi
- (Bs. 5.34)
Panthās tu koṭi-śata-vatsara-sampragamyaḥ. Just like in the material science they are trying to go to the moon planet or other planets also by certain standard of speed in the Sputnik.
(aside) It is not working?
They are finding it difficult even to go to the moon planet, which is the nearest planet to the earth. And there are innumerable other planets. And the modern scientists calculate that the highest planet, if we want to go there, it will take the Sputnik speed, which is running eighteen thousand miles per hour; in that speed if we go forty thousands of years, we can reach the highest planetary system within this material world.
But so far the kingdom of God, which is called Vaikuṇṭhaloka, or sanātana-dhāma, as it is stated in the Bhagavad-gītā, paras tasmāt tu bhāvo 'nya 'vyakta 'vyaktāt sanātanaḥ (BG 8.20). That is sanātana-dhāma. There is—we get this information from the Bhagavad-gītā—the kingdom of God, where everything is permanent. Within this material world, everything is non-permanent, temporary.
