First answer (1).
Preface: tools in creation:
Chakira- Nivdalim the tools themselves are creations.
Kabalah- Netiyos (Sefiros) the tools are themselves G-dly.
The difference: if the tools are creations there will be in-exactitude in the creations (not due to the creator but) due to the limitations of the tools.
If the tools are “G-dly” they are perfect and the product (the creation) will accordingly be perfect.
Havaya Hu HaElokim because this is Kabbalah and there is exactness in the meeting between the two. MP3
