3577. 'Like the odour of the field' means as the good ground from which truth is acquired. This is clear from the meaning of 'the odour of the field' as the perception of truth acquired from good, like the scent from the harvest in the field - 'the field' meaning good ground, see 3500. The reason 'odour' means perception is that all the delight that good yields and all the pleasantness that truth gives, which people perceive in the next life, also manifest themselves there as corresponding odours, see 1514, 1517-1519. From this and from correspondences it is evident that 'odour' is nothing else than the power of perception, though a natural power of perception corresponding to a spiritual power of it.

1514. Spheres are also made perceptible to the senses by means of odors, which spirits smell far more keenly than men do; for, remarkably, odors correspond to spheres. With people who have given themselves up to the practice of deceit and have as a consequence acquired a deceitful disposition, there is a stink of vomit when their sphere is converted into an odor. With those who have studied how to speak eloquently so that it may all lead to self-admiration, their sphere when converted into something odoriferous is like the smell of burnt bread. With those who have given themselves up to the pursuit of mere pleasure and with whom no charity or faith has existed, the odor of their sphere is that of excrement. It is similar in the case of those who have gone through life committing adultery, whose odor is even more obnoxious. With those who have led lives of intense hatred, of revenge, and of practicing cruelty their sphere, when converted into odors, is the stench of a corpse. From those who have been disgustingly avaricious the stench of mice is given off, and the stench of house-lice or bugs comes from those who persecute the innocent. These odors cannot be detected by anyone unless his interior senses have been opened in such a way that he is at the same time in the company of spirits.
