Is the very world of material substance real?

You are so grounded in materiality that you do not realise that at the last, there can be nothing more unreal—more dreamlike—more transitory—more phantasmal—than this very world of material substance. 

You are not aware that in your very world of material substance, there is absolutely no permanence—

The mind itself is not quick enough to catch a glimpse of material reality, for, before the mind can grasp a material fact, the fact has merged into something else. 

The world of mind, and still truer, the world of spirit is far more real than is the world of materiality. 

From the spiritual viewpoint, there is nothing at all real, but spirit, and matter is regarded as the most fleeting and unreal of all illusory appearances. 

From the same viewpoint, the higher in the scale you rise above the material plane, the more real becomes the phenomena experienced. 

Therefore, it follows that the experiences of the soul on the higher Astral are not only not unreal in nature, but by comparison are far more real than the experiences of life on the material plane. 

Nature is not cheated on the Astral—

Nature herself manifests with more real effect on that plane than on the material plane.
