What is consciousness? what is the substance of consciousness? is it material or immaterial, mortal or immortal? how is it connected with a body? has it a particular seat in any particular body as the brain does? is consciousness synonymous with mind? is it eternal and non-local? these questions have interested thinkers for many centuries. it is the object of this book to demonstrate, through a series of cases reported across the world at various times relating to many curious mind-related phenomena like the creation of mental entities, the imprints of indelible images on the human body, stigmata, birthmarks and bodily deformities corresponding to the injuries sustained in the previous life, thought-photography, materialization experiments etc., that: human mind can bring into being thought-forms and can exteriorize them, giving them some objective consistency.
