Every thing you see exist because it was dreamed/imagined first.
Don't just agree with me. Participate. Make sure you are convinced.
Search the items of your surroundings... can you find one that was not first dreamed?
Most of the items we encounter are the dreams of mankind... the computer, the house,
cars and roads, buildings, appliances, tools, dinnerware, books... etc.
Some things we encounter are "natural"... rocks, trees, birds, clouds...
these are not the dreams of mankind, but of something else.
To quote Paracelsus:
Paracelsus - "A strong will subdues a weaker one, and therefore the first necessary condition for the purpose of producing magic effects is the development of the will."
