In Life in the World Unseen, Robert Hugh Benson, who passed in 1914 provides descriptions of the physical nature of the spirit world, which he recorded through Anthony Borgia sometime after he passed. Robert’s biography is found on Wikipedia.
In part II of the book, Robert describes the flowers, soil and water. The book is available for free in a PDF format here.
Here is an excerpt from the book (PART II – The World Unseen I. THE FLOWERS Page 56):
“When we are first introduced to the flowers and trees and all the luxuriance of spirit nature, we instantly perceive something that earthly nature never seemed to possess, and that is an inherent intelligence within all growing things. Earthly flowers, although living, make no immediate personal response when one comes into close touch with them. But here it is vastly different.
Spirit flowers are imperishable, and that should at once suggest more than mere life within them, and spirit flowers, as well as all other forms of nature, are created by the Great Father of the Universe through his agents in the realms of spirit. They are part of the immense stream of life that flows directly from Him, and that flows through every species of botanic growth. That stream never ceases, never falters, and it is, moreover, continuously fed by the admiration and love which we, in this world of spirit, gratefully shed upon such choice gifts of the Father.
Is it, then, to be wondered at, when we take the tiniest blossom within our hands, that we should feel such an influx of magnetic power, such a revivifying force, such an upliftment of one’s very being, when we know, in truth, that those forces for our betterment are coming directly from the Source of all good? No, there is no other meaning behind our spirit flowers than the expressed beauty of the Father of the Universe, and, surely, that is enough. He has attached no strange symbolism to His faultless creations. Why should we?
A large majority of the flowers are not meant to be picked. To pick them is not to destroy them—it is to cut off that which is in direct contact with the Father. It is possible to gather them, of course; no disastrous calamity would follow if one did. But whosoever picked them would certainly regret it very deeply. Think of some small article that you possess and treasure above all your other earthly possessions, and then consider deliberately destroying it. It would cause you extreme sadness to do so, although the loss incurred might be intrinsically trifling. Such would be your emotions when you heedlessly culled those spirit flowers that are not intended for gathering.
But there are blooms, and plenty of them, that are expressly there to be picked, and many of us do so, taking them into our houses just as we used to do on earth, and for the same reason.
These severed flowers will survive their removal for just so long as we wish to retain them. When our interest in them begins to wane they will quickly disintegrate. There will be no unsightly witheredremnants, for there can be no death in a land of eternal life. We simply perceive that our flowers have gone, and we can then replace them if we so wish.”
Please note, that not all of us pass into such beautiful surroundings, as we all vary in our condition of love, which determines where we will live. So there are much darker places which are called the hells, than that described by Robert here. There are also much more beautiful places that we can progress into. This is clearly described by many spirits in including Jesus, in the Book of Truths also called the Padgett Messages, channeled by James E. Padgett between 1914 and 1918.
