We cannot even go to the end of the universe, so how can we go to the spiritual world?

 

„We living entities, we are spiritual atoms, and by material atomic combination we have developed this body, although this material body is foreign to me. Similarly, we can develop our spiritual body also in the spiritual world. Is it clear? Just like in the material world, in combination with matter we have developed this material body. Do you believe in this, that "I am spiritual atom, and I have developed this material body on the basis of spiritual atom?" It is a fact. It is a fact.

Just like in the mother's womb when the spiritual atom takes place, then it grows, it forms the material body. Without that spiritual atom, there cannot be any growth of body. Simply sex intercourse does not give guarantee of pregnancy. Unless that spiritual atom is there, the body does not grow.” (Lecture on BG 4.11-12 -- New York, July 28, 1966)

 

„A man can go to the higher planetary system when he is preparing himself to go there. So there are millions and trillions of planets. Wherever you want, you can go. The descriptions are there in the śāstra. But there is another description, the kingdom of God. That kingdom of God is there beyond this material sky. So we have to take information where that spiritual world is there. You can have it from Vedic literature. In the Bhagavad-gītā it is said, paras tasmāt tu bhāvo 'nyo 'vyakto 'vyaktāt sanātanaḥ (BG 8.20). There is another nature, the spiritual nature, which is beyond this material nature. That material nature... Vyaktāvyakta means some portion is manifested and some portion is not manifested. And we get information from Bhagavad-gītā that the spiritual nature is beyond this manifested and nonmanifested cosmic situation. So Kṛṣṇa says, the supreme authority says, mad-yājino 'pi yānti mām (BG 9.25). If somebody cultivates Kṛṣṇa consciousness, he can go there. It is not difficult; simply you have to change your mode of life.” (Lecture on BG 2.12 -- Mexico, February 12, 1975)

 

„We are eternally connected with the Supreme Lord, but somehow or other we are now in material contamination. Therefore, we must take up a process by which to go back again to the spiritual world. That linking process is called yoga. The actual translation of the word yoga is "plus." At the present moment we are minus God, or minus the Supreme. But when we make ourselves plus—connected—then our human form of life is perfect. During our lifetime we have to practice approaching that point of perfection, and at the time of death, when we give up this material body, that perfection has to be realized. At the time of death, one must be prepared. Students, for instance, prepare for two to five years in college, and the final test of their education is the examination. If they pass the examination, they get a degree. Similarly, in the subject of life, if we prepare for the examination at the time of death and pass it, then we are transferred to the spiritual world. Everything is examined at the time of death.

There is a very common Bengali proverb that says that whatever one does for perfection will be tested at the time of his death. Bhagavad-gītā describes what we should do at the point of our death, when we are giving up this present body.” (Easy Journey to Other Planets)
