You have made some very significant disclosures about your present situation, interests, and motivations. Many of us know firsthand how challenging it can be to have one's faith shaken, how difficult it is to try to gain an orientation in life as an agnostic, or otherwise to try to understand one's place in the world without divine guidance.
Among the aims of the teachings of the traditional school are the restoration of faith and the restitution of the saving barque of prayer. It is very common that the simple but entirely adequate faith inherited from one's parents is incapable of withstanding the tenaciousness of the ego fortified by modern ideologies born from the academy, the microscope and telescope, and the examination room. This is not to say that modern modes and means to knowledge are inherently evil or without tangible benefit, but simply that they are fundamentally inadequate to fully meet the needs of the human soul, to convey an accurate assessment of man's place in the world, or to communicate the knowledge of our ultimate destination at the end of our sojourn on earth.
The traditional authorities combat these limited modes of knowing by restating and in some cases restoring the metaphysical teachings of religion and tradition in a manner that is meaningful and accessible to contemporary men and women who have been influenced by these ideologies and their attendant rational disequilibrium. To quote Frithjof Schuon writing in his book Understanding Islam,
"This book [and indeed most of the books of the traditional school] is intended primarily for Western readers given the language in which it is written and the nature of its dialectic, but there are doubtless some Orientals, of Western formation — men who have perhaps lost sight of the solid grounds for faith in God and Tradition — who equally may be able to profit from it and in any case to understand that Tradition is not a childish and outmoded mythology but a science that is terribly real."
Platonism, Hermetism, and Egyption Philosophical Theology, are all very interesting and valuable subjects. It was through a powerful encounter with Plato and Hermes (and a few others), for example, that I first learned to distinguish between orthodoxy and heterodoxy in religious and psuedoreligious teachings. If you are interested in obtaining assistance with your stated dilemmas, including the desire for orientation and a deeply rooted conflict related to your understanding of exclusivity and universality in religion, you may find the teachings of the traditional school to be of inestimable value.
