10293. 'And onycha' means an affection for truth on the more internal natural level. This is clear from the meaning of 'sweet-smelling onycha' as an affection for natural truth; 'onycha' means that truth, while 'sweet-smelling' means the perception of what is pleasing, which springs from the affection for truth, and so means the affection itself. The reason for calling it 'sweet-smelling' onycha is that it is described as such both before and after the listing of these spices, in the words, 'Take for yourself sweet-smelling spices, stacte and onycha and galbanum - sweet-smelling ones'. The reason why an affection for truth in the natural is what is meant by 'onycha' is that this spice is mentioned second; for the spices are mentioned in the order in which the different kinds of truth are present with a person, from the most external to the inmost levels of them. Consequently 'stacte' means an affection for truth on the level of the senses, which is the most external kind of truth; 'onycha' means an affection for truth on the natural level, which is interior truth within the natural man; 'galbanum' means an affection for truth on a still more internal level, which is interior truth within the spiritual or internal man; and 'frankincense' means truth on the inmost level within the internal man, which is spiritual good. They have a similar meaning to the spices that the anointing oil consisted of, which were the best myrrh, sweet-smelling cinnamon, sweet-smelling calamus, and cassia. These too mean those levels of truth in that same order, see 10252, 10254, 10256, 10258; but the difference is that the kinds of truth meant by the spices of the anointing oil belong to the celestial group, whereas those meant by the spices of the incense belong to the spiritual group, a subject dealt with above in 10254, 10291.

I once perceived an odor of wine, and I was told that it came from those who, out of friendship and love that is lawful, endear themselves, so that truth also is contained within their endearing words and actions. There is much variety of this odor, and it derives from the sphere of true courteousness.
