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.
The Primordial Substance is perfectly equal to the Absolute One, Spirit-Consciousness, but it is not the Spirit in Se.
To the mind of man, this eternal and real union between Spirit in Se and Primordial Substance remains a mystery.
The universal movement is called Ired.
It is the Unique Law –as a zero point in the immense space.
Any law depends on it and converges on it.
Here an example may be necessary: If you blow a ball up, and fill it with air, and later you blow it up again with more and more strength, the new air presses against the previous air, and this pressure changes the form of the air inside the balloon, by compressing and expanding it.
