While the spiritual plane, as mentioned previously, is one of light and happiness, the physical plane, on the other hand, is intended to give the individual or the living being the opportunity to experience the culmination of the darkness of suffering that is absolutely essential in order that the being can experience the culmination of light on the spiritual plane of existence. Without contrasts, there can be no sensory perception or experience. But in order that there can be the opportunity for real, true experience of the culmination of light in its purest form and true experience of the culmination of darkness in its purest form, these forms of experience must each necessitate their own particular spheres of manifestation. If the opposite were the case, a plane of light in its purest form would be an impossibility, just as a plane of darkness in its purest form would also be an impossibility. A true "paradise" or an absolutely perfect existence would thereby also be impossible. These two planes of existence must therefore of necessity be two separate areas of life experience.
