'Many of the islands off the west coast of Britain, including Lundy were known to the Celts as 'Isles of the Dead'. They were regarded as holy islands which formed gateways to the otherworld and to which the illustrious dead were ferried, there to be buried with solemn rite amid the spirits of their forefathers.' - A.F. Langham, The Island of Lundy.

'One of the chief recurrent images of Celtic mythology and legend is a visit to or from the 'Otherworld' - a realm somehow detached from this present world, or at most times, to all but a chosen few, invisible. It may be visibly cut off by ocean, river, lake, by mountain rock, or by mist, or hidden within the mountain itself. Sometimes it can only be entered by the overcoming of a test or through the sustaining of a mortal wound. Always cut off by some sort of barrier from the world of earthly existence.' - At The Table of the Grail   Hannah Closs 

There is something about the use of the word 'white' which denotes a special holiness above and beyond the colour. In the gospels, in Welsh legends the Otherworld has been called GWYNNWESI - 'the WHITE or BLISSFUL ABODE' and ' GWAS GWYN' - THE WHITE MANSION, the mythical abode of the happy dead. 

'The 'Otherworld' is the internal resonance of the everyday world; it exists out of time, simoultaneously cross intersecting all times and is thus accessible to visitation from any point in linear time.'------------Caitlin Mathews.

'Within the 'Otherworld', archetypal forces are perceptible, essential wisdom teachings are available to those who have the right keys; it is the realm of quest and achievement. of challenge and encounter, of initiation and enlightenment. it is not illusory, a figment of imagination or an anthropological invention. It is not heaven, hell or analogous to any drug-induced vision. The 'Otherworld' is the mythological reality or symbolic continuum within which we can encounter the archetypal energies of the gods and their acts.'------------Caitlin Mathews.

'The 'Otherworld' has its own valid reality which is not accessible to the five senses, though it is appreciable by the sixth. It is often spoken of as a state of conciousness.'------------Caitlin Mathews.

'The 'Otherworld' exists in its own right, is consistent to its own rules and as a visitable reality is not merely confined to specially phsycic people.'------------Caitlin Mathews.
