A.--'I have always made a distinction between pictures seen in the memory of nature and visions of actual beings now existing in the inner world. We can make the same distinction in our world: I may close my eyes and see you as a vivid picture in memory, or I may look at you with my physical eyes and see your actual image. In seeing these beings of which I speak, the physical eyes may be open or closed: mystical beings in their own world and nature are never seen with the physical eyes.' _Otherworlds._-- Q.--By the inner world do you mean the Celtic Otherworld? A.--'Yes; though there are many Otherworlds. The _Tír-na-nog_ of the ancient Irish, in which the races of the _Sidhe_ exist, may be described as a radiant archetype of this world, though this definition does not at all express its psychic nature. In _Tír-na-nog_ one sees nothing save harmony and beautiful forms. There are other worlds in which we can see horrible shapes.' _Classification of the 'Sidhe'._-- Q.--Do you in any way classify the _Sidhe_ races to which you refer? A.--'The beings whom I call the _Sidhe_, I divide, as I have seen them, into two great classes: those which are shining, and those which are opalescent and seem lit up by a light within themselves. The shining beings appear to be lower in the hierarchies; the opalescent beings are more rarely seen, and appear to hold the positions of great chiefs or princes among the tribes of Dana.' _Conditions of Seership._-- Q.--Under what state or condition and where have you seen such beings? A.--'I have seen them most frequently after being away from a city or town for a few days. The whole west coast of Ireland from Donegal to Kerry seems charged with a magical power, and I find it easiest to see while I am there. I have always found it comparatively easy to see visions while at ancient monuments like New Grange and Dowth, because I think such places are naturally charged with psychical forces, and were for that reason made use of long ago as sacred places. I usually find it possible to throw myself into the mood of seeing; but sometimes visions have forced themselves upon me.' _The Shining Beings._-- Q.--Can you describe the shining beings? A.--'It is very difficult to give any intelligible description of them. The first time I saw them with great vividness I was lying on a hill-side alone in the west of Ireland, in County Sligo: I had been listening to music in the air, and to what seemed to be the sound of bells, and was trying to understand these aerial clashings in which wind seemed to break upon wind in an ever-changing musical silvery sound. Then the space before me grew luminous, and I began to see one beautiful being after another.' _The Opalescent Beings._-- Q.--Can you describe one of the opalescent beings?
