Torah and Hhokhma
We call this Torah.
And there is Tora min Ha’aretz, ‘Instruction from Earth’.
We call this Hhokhma ("Wisdom").
Torah is given in Revelation;
it needs to be delved into, to understand its Godly secrets.
Hhokhma is built on Logic, Emotion and Experience;
it needs to be constructed, to develop its human truths.
When we say that Instruction from Heaven is holy and that Instruction from Earth is not, we're only talking about degrees. We were created in the image of God. Our world was built by God, piece by piece, eon by eon. When we examine our world, we are examining God's creation. When we examine ourselves, we are examining shadows cast by God's flame.
Torah comes down from Heaven to Earth.
Hhokhma rises from Earth to Heaven.
If you've only got one, you've only got half the picture.
