Only you yourself could now let down the bars for the inrush of evil and irresponsible spiritual intelligences, and if you should inadvertently let down the bars we should rush to put them up again. We have some authority out here. Yes, even so soon I can say that. Are you surprised? LETTER XXVIII EXCEPT YE BE AS LITTLE CHILDREN I ONCE heard a man refer to this world as the play world, “for,” said he, “we are all children here, and we create the environment that we desire.” As a child at play can turn a chair into a tower or a prancing steed, so we in this world can make real for the moment whatever we imagine. Has it never filled you with amazement, that absolute vividness of the imagination of children? A child says unblushingly and with conviction, “That rug is a garden, that plank in the floor is a river, that chair is a castle, and I am a king.” Why does he say these things? How _can_ he say these things? Because--and here is the point--he still subconsciously remembers the life out here which he so lately left. He has carried over with him into the life of earth something of his lost freedom and power of imagination. That does not mean that all things in this world are imaginary--far from it. Objects here, objects existing in tenuous matter, are as real and comparatively substantial as with you; but there is the possibility of creation here, creation in a form of matter even more subtle still--thought-substance. If you create something on earth in solid matter, you create it first in thought-substance; but there is this difference between your creation and ours: until you have moulded solid matter around your thought-pattern you do not believe that the thought-pattern really exists save in your own fancy. We out here can see the thought-creations of others if we and they will it so. We can also--and I tell you this for your comfort--we can also see your thought-creations, and by adding the strength of our will to yours we can help you to realise them in substantial form. Sometimes we build here bit by bit, in the four-dimensional world, especially when we wish to leave a thing for others to see and enjoy, when we wish a thing to survive for a long time. But a thought-form is visible to all highly developed spirits. Of course you understand that not all spirits are highly developed. In fact very few are far progressed; but the dullest man out here has something which most of you have lost--the faith in his own thought-creations. Now, the power which makes creation possible is not lost to a soul when it takes on solid matter again. But the power is gradually overcome and the imagination is discouraged by the incredulity of mature men and women, who say constantly to the child: “That is only play; that is not really so; that is only imagination.”
