How does one say "I" or I AM in Hebrew?

[lenvdb64]

<<Which also means Yahweh?>>

Nope - this does not, as Yahweh is another deity (or rather an emanation of the ALL) in the Hebrew Pantheon of Gods.

In the Tree of Life there are 10 spheres, (Sephirot / realms/ heavens / dimensions)

Each of the heavens has its own order of angels, ruling archangel, deity (or emanation of God) and associated symbols.

In Kether the ruling archangel is Metatron and the deity is "Eheyeh"
In Chockmah the ruling archangel is Ratziel and the Deity is "YHWH"
In Binah the ruling archangel is Tzafkiel and the deity is YHWH ELohim...etc etc etc.

These aspects of God are also imprinted on us at soul level in the Microcosm.

Nice what Miss Hepburn added as well.

What we are really after is a vibration, an energy.
It is difficult for us to correctly pronounce the god name since its correct vibration was lost over time. Other names come close. We are after the energy and vibration the name represents, and with our limited capacity it is not easy.

I love doing this as an exercise, whereby I intone (vibrate) the sacred names, and experience the energy and vibration it releases. It is one way of becoming familiar with the deity and its energy/vibration.
