{Footnote 1} In the Word the Lord is called an angel (n. 6280, 6831, 8192, 9303).  A whole angelic society is called an angel, and Michael and Raphael are angelic societies, so called from their functions (n. 8192).  The societies of heaven and the angels have no names, but are distinguished by the quality of their good, and by the idea of it (n. 1705, 1754).

53.  As an entire society is a heaven in a smaller form, so an angel is a heaven in the smallest form.  For heaven is not outside of the angel, but is within him, since the interior things which belong to his mind are arranged into the form of heaven, thus for the reception of all things of heaven that are outside of him.  These also he receives according to the quality of the good that is in him from the Lord.  It is from this that an angel is a heaven.

54.  It can in no sense be said that heaven is outside of any one; it is within him.  For it is in accordance with the heaven that is within him that each angel receives the heaven that is outside of him.  This makes clear how greatly misled is he who believes that to come into heaven is simply to be taken up among angels, without regard to what one’s interior life may be, thus that heaven is granted to each one by mercy apart from means;{1} when, in fact, unless heaven is within one, nothing of the heaven that is outside can flow in and be received.  There are many spirits who have this idea.  Because of this belief they have been taken up into heaven; but when they came there, because their interior life was contrary to the angelic life, their intellectual faculties began to be blinded until they became like fools; and they began to be tortured in their voluntary faculties until they became like madmen.  In a word, if those that have lived wickedly come into heaven they gasp for breath and writhe about, like fishes out of water in the air, or like animals in ether in an airpump when the air has been exhausted.  From this it can be seen that heaven is not outside of a man, but within him.{2}

{Footnote 1} Heaven is not granted from mercy apart from means, but in accordance with the life; yet everything of the life by which man is led to heaven by the Lord belongs to mercy; this is what is meant by mercy (n. 5057, 10659).  If heaven were granted from mercy apart from means it would be granted to all (n. 2401).  About some evil spirits cast down from heaven who believed that heaven was granted to everyone from mercy apart from means (n. 4226).

  {Footnote 2} Heaven is in man (n. 3884).

55.  As everyone receives the heaven that is outside of him in accordance with the quality of the heaven that is within him, so in like manner does everyone receive the Lord, since it is the Divine of the Lord that makes heaven.  And for this reason when the Lord becomes manifestly present in any society His appearance there is in accord with the quality of the good in which the society is, thus not the same
