For the materialist, wedded to the physical consciousness and the physical senses, anything that is not able to be perceived and validated by the physical senses (or extensions of those senses developed through science and technology) is considered to be less real, or even purely illusory. Thus, the idea that acknowledges the existence of a vital world, a mental world, a psychic world, a spiritual world, is considered to be something fictitious and the product of some kind of mental illness or imbalance.
It becomes clear, however, that this viewpoint, far from being the truth of existence, actually is simply ignorance. In his play, Hamlet, Shakespeare alludes to this with the famous line “There are more things in heaven and earth, Horatio, than are dreamt of in your philosophy.”
At the same time, it is easy for the material consciousness to try to ridicule those who claim psychic vision or powers, because of the vast amount of confusion, not to speak of outright fraud, that has occurred during the development and expression of these as yet mostly latent or at least subliminal forms of perception.
Sri Aurobindo explores the reality of the psychic awareness: “The range of the psychic consciousness and its experiences is almost illimitable and the variety and complexity of its phenomena almost infinite. … all the physical senses have their corresponding powers in the psychical being, there is a psychical hearing, touch, smell, taste: indeed the physical senses are themselves in reality only a projection of the inner sense into limited and externalised operation in and through and upon the phenomena of gross matter. The psychical sight receives characteristically the images that are formed in the subtle matter of the mental or psychical ether, cittakasa. These may be transcriptions there or impresses of physical things, persons, scenes, happenings, whatever is, was or will be or may be in the physical universe. These images are variously seen and under all kinds of conditions; in Samadhi or in the waking state, and in the latter with the bodily eyes closed or open, projected on or into a physical object or medium or seen as if materialised in the physical atmosphere or only in a psychical ether revealing itself through this grosser physical atmosphere; seen through the physical eyes themselves as a secondary instrument and as if under the conditions of the physical vision or by the psychical vision alone and independently of the relations of our ordinary sight to space. The real agent is always the psychical sight and the power indicates that the consciousness is more or less awake, intermittently or normally and more or less perfectly, in the psychical body. It is possible to see in this way the transcriptions or impressions of things at any distance beyond the range of the physical vision or the images of the past or the future.”
