Answer: Our world is not a barrier when it comes to feeling the whole creation. You don’t feel the whole world now, the whole system, but you will be able to do so with time. An internal attribute will be revealed in you by which you will feel the whole universe while still living in this world.
Then you will leave this life and will feel the world not only through your body. The reason is that we don’t feel the upper world through the body but by senses that are created through the soul. When you leave the corporeal body, the soul doesn’t undergo any changes and will continue your spiritual path, your development, just the way it is even without a body.
Therefore, it is important that you discover the Creator once while living in your body and then you will be able to move onward.
