A little more insight on the concept of names of G-d... I have explained that the name is not the essence, it is a mere description of the relationship with the other.
http://vbm-torah.org/archive/kuzari/28kuzari.htmThe Attributes When R. Yehuda Halevi approaches the issue of the names and attributes of God, he is forced to deal with the issue of the corporeality of God and the question that arises from the very assignation of a name.[1]
The Rabbi said: All names of God, save the Tetragrammaton, are predicates and attributive descriptions, derived from the way His creatures are affected by His decrees and measures. He is called merciful if he improves the condition of any man whom people pity for his sorry plight. They attribute to Him mercy and compassion, although this is, in our conception, surely nothing but a weakness of the soul and a quick movement of nature. This cannot be applied to God, who is a just Judge, ordaining the poverty of one individual and the wealth of another. His nature remains quite unaffected by it. He has no sympathy with one, nor anger against another. We see the same in human judges to whom questions are put. They decide according to law, making some people happy, and others miserable. He appears to us, as we observe His doings, sometimes a "merciful and compassionate God" (Shemot 34:6), sometimes "a jealous and vengeful God" (Nachum 1:2), while He never changes from one attribute to the other. (II, 2) Rihal emphasizes that the various attributes do not testify to changes in God Himself, but to man's perspective on God. Rihal illustrates the point with the example of a judge who, with respect to the very same verdict, appears "merciful and compassionate" to one party and "jealous and vengeful" to the other. In the same manner, the diverse attributes assigned to God by man from his perspective do not attest to changes in God, but to the manner in which subjective man comprehends His objective revelation.
Moreover, Rihal notes the problem that rises from the fact that the terminology that we use to describe God is taken from the human realm and from man's emotional and intellectual concepts. As such, they do not faithfully reflect God's actions.
Having said this, Rihal moves on to a detailed classification of the various Divine attributes:
All attributes (excepting the Tetragrammaton) are divided into three classes, creative, relative, and negative. As regards the creative attributes, they are derived from acts emanating from Him by ways of natural medium, e.g. "making poor and rich," "exalting or casting down," "merciful and compassionate," "jealous and revengeful," "strong and almighty," and the like. As regards the relative attributes, "Blessed, praised, glorified, holy, exalted, and extolled," they are borrowed from the reverence given to Him by mankind. However numerous these may be, they produce no plurality as far as He is concerned, nor do they affect his Unity. As regards the negative attributes, such as "Living, Only, First and Last," they are given to Him in order to negate their contrasts, but not to establish them in the sense we understand them. For we cannot understand life except accompanied by sensibility and movement. God, however, is above them. We describe Him as living in order to negate the idea of the rigid and dead… Thus, the essence of God is too exalted to have anything to do with life or death, nor can the terms light or darkness be applied to it. If we were asked whether this essence is light or darkness, we should say light by way of metaphor, for fear one might conclude that that which is not light must be darkness. As a matter of fact, we must say that only material bodies are subject to light and darkness, but the Divine essence is no body, and can consequently only receive the attributes of light or darkness by way of simile, or in order to negate an attribute hinting at a deficiency. (II, 2)
