9994. 'And unleavened wafers anointed with oil' means what is celestial in the external man. This is clear from the meaning of 'wafers' as what is celestial in the external man, dealt with below; from the meaning of 'unleavened' as what has been purified, dealt with above in 9992; and from the meaning of 'oil' as the good of love, dealt with in 886, 4582, 4638. From these meanings it is evident that 'unleavened wafers anointed with oil' means what is celestial in the external man, which proceeds in order from the first two. The wafers are said to be 'anointed with oil' but the cakes 'mixed with oil' because the wafers are third in order and the cakes second, as stated immediately above in 9993. What is second in order proceeds directly from the inmost and consequently has the inmost celestial within it, meant by 'oil'; and what is third in order proceeds indirectly from the inmost, that is to say, through what is second in order, and does not consequently have the inmost within it in quite the same way as that second in order. So it is that the cakes, since they mean the celestial that is second in order, are said to be 'mixed with oil', whereas the wafers, since they mean the celestial that is third in order, are said to be 'anointed with oil'. But these matters are hardly intelligible to anyone unless he knows something about the way things come into existence in succession; this has the same relation as end, cause, and effect. What is inmost constitutes the end, what is in the middle constitutes the cause, and what stands last constitutes the effect. The end must be within the cause if this is to be the cause belonging to that end, and the cause must be within the effect if this is to be the effect belonging to that cause. The end is not apparent within the effect as it is within the cause, because the effect lies further away from the end than the cause does. All this may enlighten the mind to recognize the nature of the inmost, middle, and external following one another in successive order.

Oil -- typically olive oil -- symbolizes the good that comes from celestial love. Celestial love is love of the Lord, the highest and purest love we can have. The good of celestial love is the desire to be good springing from celestial love: Wanting to do the Lord's will because you love Him. That's not a state many reach, even in heaven, but it's a beautiful goal. This representation makes sense based on the idea that the sun -- the source of all natural light and heat, and thus all natural life -- represents the Lord, the source of all spiritual light, heat and life. Burning oil was the most pure fire available in Biblical times, thus the closest representation of the sun people could create.
