This line is especially interesting to me. Aiwass/Nuit is asking the reader to recognize that they are a part of her, and thus Hadit. Hadit being the secret centre of the heart (the point in the middle).
The part that is especially interesting to me is that she describes Hadit as her tongue. This would reinforce what we've discussed previously about Hadit being the manifestation of Nuit, the tongue being an organ of expression and revelation. In part, I read it again as a call to evangelism.
But most interesting to me, in Chinese Medicine the tongue is seen as the flowering of the Heart. In a way the physical tongue is seen as continuous with the physical heart. The Heart contains the Shen, the ruler of the 5 spiritual parts of us (one for each element, of which there are 5 in Chinese medicine). The Shen is the Fire spirit and one of the ways it expresses itself is through speech (the tongue).
Its associated with the planet Mars, which for me then links the Tongue/Heart/Hadit/Horus, back to the Tower//Mars/Mouth/Peh/Ra-Hoor-Kuit/Horus, as a card of revelation. The Father and Son, the Tongue and the Mouth.
