Dream Sutra: Perceiving Hidden Realms

Defying logic and conjuring hidden worlds is the realm of dreams. For thousands of years, philosophers, scientists and spiritualists alike, have struggled to add a process parameter to the existence of the dream state. There are dictionaries galore trying to translate dream language into the vocabulary of the waking state. So far, it has been nothing more than an attempt at best. And so is this text.
The only saving grace is that the collection and analysis of this subject is a combined effort of several people who share a common subject of spiritual evolution and who have a common Guru - a very powerful and accomplished guide who practised astral travel at will (I have been a witness on several occasions). Often, he would give instructions, messages and interact with his disciples and devotees in their dreams.
