Tumah
According to the Kabala, physical or moral uncleanness. The latter is divided into three main divisions idolatry, murder, and immorality. Sin, says the same authority, not only rendered imperfect man himself, but also affected the whole of nature, even to the sphere of angels, and the Divinity himself. In physical uncleanness there is a coarser and a more subtle form. The latter causes a dimness in the soul which is most keenly felt by those who are nearest to sacred things. Organic things which come into contact with the human body are more liable to the Tumah than remoter things. The human corpse is more unclean than that of the lower animals, because its more complex nature involves a more repulsive decay. Thus the corpse of a holy man is most unclean of all.
