So Bhagavad-gītā is describing what should we do at the, at the point of our death, when we are giving up this body, this present body. So for the yogis, dhyāna-yogis, this prescription is recited here, sarva-dvārāṇi saṁyamya mano hṛdi-nirudhya ca. Sarva-dvārāṇi means... This system is called pratyāhāra. In the technical language of yogic system it is called pratyāhāra. Pratyāhāra means "just the opposite." Now, the senses, my eye, my eyes are engaged in seeing the worldly beauty. Now I have to retract from enjoying that beauty, and I have to see inside the beauty. That is called pratyāhāra. Similarly, I have to hear the oṁkāra sound from within. So all the senses are to be stopped in their external activities—that is the perfection of yoga—and concentrate the mind on Viṣṇu-mūrti. Mano hṛdi. The mind is very agitating, so it has to be fixed up on the heart. Mano hṛdi-nirudhya. Nirudhya means just arresting the mind within the heart. Mūrdhni, mūrdhny ādhāyātmanaḥ prāṇam āsthito yoga-dhāraṇām. And in this way, when we transfer the air—life on the top of our head, that is the perfection of yoga. And a perfect yogi, then he fixes up where he shall go. There are innumerable planets, and beyond the planets, there are spiritual world.
So yogis, they have got information. How they have got information? From the scriptures, from Vedic literature, they have got. Just like before I came to your country I got the description of your country from the books, similarly, we can have all the description of higher planets and the spiritual world. They are mentioned there. The yogi know. The yogi knows everything, and he can transfer his self, any planet he likes. He does not require the help of any sputnik. The sputniks, they are trying for so many years, and they will go on trying for one hundred or one thousand years more. They'll never reach any planet. Be rest assured. This is not the process. This is not the process to reach another planet. Maybe, by scientific process, one man, one man or two man can reach, but that is not the general process. The general process is: if you want to transfer yourself any better planet, then you have to practice this yoga system, or jñāna system, not bhakti system. Bhakti system is not meant for any material planet.
