Journey of the Soul by Sri Srimad Bhaktivedanta Narayana Gosvami Maharaja

 
The eternal spirit soul has access to two places, this material world and the spiritual world, both of which he may seek. He is situated in svapna-sthdnam, a third realm, made of a dream state, which is located on the margin of these two worlds. From that junction he is able to see them both.
We trust various persons of authority to inform us about material subject matters, but whom shall we trust in regard to transcendental subject matters and the transcendental world? We cannot experience transcendence with any of our material senses. How then, can we have an idea of that pure reality? We can see the body, but not the soul. How can we verify that there is a soul beyond matter? Though God is everywhere, we don't see Him. How then, can we determine who is God? Although it is evident that we cannot control the world, how can we trust that there is a God from whom this creation has come, and how can we be confident that it is He who controls it? Millions of people are born daily, and millions also die. Who controls this overwhelming tide of birth and death? Sea waves come on schedule, the sun appears on schedule, and new days come with continuous regularity. We do not control those rhythms, yet somehow, everything is maintained.
