The pastimes of the Lord are happening in one place, but they are projected into different places like a TV transmission. If you have used cable TV, you tune into a channel, and you see some movie or sport going on in someplace. That movie or sport is not in the 15th century or in India. It is happening in the spiritual world. But it is projected or transmitted to different places. So, if you want to enter Krishna’s pastimes, then you can enter the spiritual world, and participate. Then, wherever that channel of pastimes is projected you will appear in that universe, at that place, and time. It is not that there are many copies of Krishna in different places. It is also not that Krishna has left the spiritual world to come and meet people in the material world. God doesn’t leave the spiritual world, and God doesn’t enter the material world. God only “appears” in the material world. That appearance is just like the sports channel appearing on your TV screen.
When Krishna appears, He comes with His entourage. He never comes alone. So if you enter Krishna’s pastimes, then if that TV channel is projected in 10 places simultaneously, you will appear in 10 places at once. It’s not that you are in 10 places. But you will “appear” in 10 places. This is how Krishna has 16,108 wives and He is with all of them. It is not that there are many copies of Krishna. It is also not that He has divided Himself, so each person gets a piece of Krishna. No. They get full Krishna. So, there is a science of how one thing appears in many places.
This TV transmission can be accessed by a devotee anytime if they become qualified. So, if you become a devotee, then you right away enter that pastime in the spiritual world, and then you are simultaneously present in many universes because factually you are not here; you are in that pastime, which is projected in other places. So, a devotee who is attached to the Lord can go to all places where the Lord goes. This “going” is not a physical entry. It is like a TV projection.
We have to understand material science to appreciate all these ideas. What you are seeing right now is also a TV projection. You are seeing the material world because of the attraction to this world. Based on what you are attracted to, you see that thing. Just like if you attracted to sports, then most of the time you are watching sports. If you are attracted to food, then most of the time you are eating. Like that the devotee who is attracted to Krishna is always seeing Krishna. He is as much there with Krishna as the food is in the hands of the person who is eating it.
So, the short answer is that don’t try to go to another universe to see Krishna. Just desire to see Krishna, and you will enter the spiritual world, and then you will be there in every universe where Krishna is conducting His pastimes. We have to give up ideas of physical movement and develop ideas about desire and attraction. Then we can understand both matter and spirit.
