Yeialel grants a penetrating and incisive intelligence, but also capable of breaking the dominion of the mind, to allow integration and harmony between mind, heart and soul. The people protected by Yeialel Guardian Angel have the talent to clearly understand the facts and the truth, which will tend to defend always and without uncertainties. Through this Angel practical intelligence reaches its highest point. Those born in these days, tuning in with their own angelic energy, will be able to give their existence the most solid structure; this task will be facilitated if the chosen profession is an intellectual one. Because of his membership in the hierarchy of the Archangelic Angels, Yeialel governs the energies of Mercury, and also because of his position in the Cosmos, the energies of Saturn. The help he provides is based on scientific truths: this Angel excludes everything that moves away from this principle.
people born these days will succeed in the sciences and professions in which the intellect proceeds slowly, with patience. They will have clear and stable ideas, on which the success granted by the angel will be based. The externalizing tendency will be placed in particular evidence and it will be typical faculty of those protected by Yeialel to know how to focus on the most suitable way to profit from a given situation. This Angel promotes the emergence of new theories concerning building, utilitarian habitat, and the practical sense of the subject will be fully expressed through the construction process. But the same angelic energy also presides over the process of material dissolution: therefore the best ambit for its protégés is in the organization of temporary activities; from prefabricated buildings and scaffolding, to exhibitions and events.
Invoked, Yeialel consoles the soul saddened by the tribulations of life, but also heals illnesses: it therefore grants health and healing (especially for the eyes), success in greatly reciprocated love, and in industry, especially metallurgy. In fact he also dominates iron and all the professions related to metallurgy in general, protecting smiths from steelworkers to the manufacturers and traders of any metal object. Regarding health, even according to the medieval text Enchiridion of Pope Leo III, his help is particularly effective in the case of eye diseases: but the protection of sight must be understood in all senses, material and even moral.
