The ib (𓄣)𐤋𐤁
 𐤋𐤁 — LB — heart / inner self 
In an Egyptian framework,  “from my heart” can be much closer to saying:
from my inner self → from my thought → from my intention → from my will → from my desire → from my feeling → from the center of my being.
The Egyptians did the modern of “heart = emotion” and “brain = thought” in the same way. The ib could encompass both feeling and intellect...
Ib and creation
This becomes especially important with Ptah...
IB — conception

thought of heart

expression / word

LOVE
Ib and the LOVE
Ib and the Duat
IB → enters the  journey → judgment → Ma'at → continuation or destruction.
And “love”
This is where we need to be precise.
But “the ib creates a female twin through romantic love” is not an ancient Egyptian teaching. That part is your own synthesis.
So for the symbolic system you've been developing,
And then your sequence can be 
LOVE → emergence → Ra → Duat → transformation → Khepri → IB → love/intention → LOVE.
