Question: What does space mean to you? Can there be unmanifested space? Does space travel or do we travel in it?
Your unmanifested space is the unknown past and the unforeseen future probabilities. When Arjun got gyan from Krishna, he travelled in the space which was hidden inside him in the layers of his subconscious, unknown to him.
Each breath that you take, connects you to your past. Therefore, you travel in space with each breath.
