Emanuel Swedenborg

“ The speech of angels is likewise full of wisdom because it proceeds from their interior thoughts, and their interior thought is wisdom, as their interior affection is love, and in their speech their love and wisdom unite. For this reason their speech is so full of wisdom that they can express in a single word what man cannot express in a thousand words also the ideas of their thought include things that are beyond man's comprehension, and still more his power of expression. ”

“ As the vowels are not essential to a language, but serve by means of tones to elevate the words to the various affections according to each one's state, so in the Hebrew tongue the vowels are not expressed, and are also variously pronounced. From this a man's quality in respect to his affection and love is known to the angels. Also in the speech of celestial angels there are no hard consonants, and it rarely passes from one consonant to another without the interposition of a word beginning with a vowel. ”

“ Speech like that in the spiritual world is inherent in every man in his interior intellectual part; but man does not know this, because this speech does not with man, as with angels, fall into words analogous to affection; nevertheless this is what causes man, when he enters the other life, to come into the same speech as spirits and angels, and thus to know how to speak without instruction. ”

“ I have been permitted to associate with them frequently, and to talk with them as friend with friend, and sometimes as stranger with stranger; and as I was then in a state like theirs I knew no otherwise than that I was talking with men on the earth. ”

“ This was tried but they could not do it, because they can utter nothing except what is in entire agreement with their affections; whatever is not in agreement is repugnant to their very life, for life belongs to affection, and their speech is from their life. ”

“ Because it is especially in tones that affections express themselves, so in human speech, when great subjects are discussed, such as heaven [caelum] and God [Deus] , those words are preferred that contain the vowels u and o; and musical tones, whenever such themes are to be expressed, rise to the same fullness; but not when less exalted themes are rendered. By such means musical art is able to express affections of various kinds.
242. In angelic speech there is a kind of symphony that cannot be described ”

“ Angelic language has nothing in common with human languages except certain words that are the sounds of a specific affection; yet this is true not of the words themselves but of their sounds; on which subject something will be said in what follows That angelic language has nothing in common with human languages is evident from the fact that angels are unable to utter a single word of human language. ”

“ Also all the particulars of angelic thought, and thus of angelic speech, appear when presented to view like a thin wave or circumfluent atmosphere, in which are innumerable things in their order derived from angelic wisdom, and these enter another's thought and affect him. The ideas of thought of everyone, both angel and man, are presented to view in the light of heaven, whenever the Lord pleases. [4] ”
