Natural reason can investigate a little by itself about Divine Mysteries.
A man knows God in a nominal way, but his reason, through constant and fervent desire of investigating the nature of God, may have a confuse knowledge in its magnetic mental field.
The Non-Manifested One does not admit definition or refusal, because by refusing or affirming it, one would establish a differential tenet, even in its Absolute aspect, and this cannot be.
The Divine Manifestation is the Absolute Principle of the Universe. Usually it is named God, or HES. God is His own essence and existence, and He alone knows Himself. “Ego sum qui sum” (“I am who I am”).
Necessarily, one must believe in a personal God, Analogical Contrariety of the Impersonal One.
Of course, the existence of God cannot be proved a priori, since we only have a nominal knowledge about God.
Masters of Theology have divided the concept of Creation into two great theories, since certain Masters teach that the Universe co-exists with God and is eternal as God; and others teach that the Universe has been created by God, not from the Eternity, but in tempore, in the time.
In His Manifestation, God is an Absolute, Eternal and Unknowable Principle. In trying to explain the Divine Trinity, one does not reflect about how, when or why the differentiation has been made and the Non-Manifested One has become Manifested.
God, in se, is cause with no cause, Unknowable.
God, as Creator, is the Divine Trinity, unknowable as to His causes, but accessible as to His effects. God-Creator possesses the Unique Idea and the knowledge about the purpose of the Universal Creation pre-exists in His Divine Intelligence.
When the sages of Hes understood the immensity and greatness of the Creation and the wonderful analogy between Macrocosm and Microcosm, and between God and man, and noticed that the purpose of man is to come close to God, also they understood the need of manifesting externally the inner power of the soul with all of its attributes to become a medium to divinizing man.
The imperfect mind of man needs a Revelation from a higher mind to affirm the revealed truth and know the divine laws, since he does not possess sufficient intrinsic media within his reach to know clearly this Revelation.
Solar Initiates of First Category are those who convey the Revelation of the Idea-Mother of the entire Race.
This Revelation was conveyed in the beginning of the Aryan Race.
The Teaching cites three names of Solar Initiates of First Category: The Manu, Teti and Noah.
