Ah thanks Will, so Mullin later corrected the translation.
But the text still says Tara dissolves into you at the end. There's no way it's a mistranslation. But, all three versions only have one visualization either front or self not both.
What the heck.
Too lazy to find my copy of Mullin's Lower Tantras book to compare, besides you need a lama to orally answer this best.
As I read the sadhana in the Selected Works volume, Tara does not
dissolve into you at the end, but much earlier. First you symbolically become the form of Tara; then you invoke Tara & other Wisdom Beings & they appear before you, next they merge with you the Symbolic Tara. Next initiatory beings begin filling you with nectar & then Amitabha appears above your head... etcetera.
At the end you are making offerings to yourself as Tara, so only a good lama can explain to you why you blend with Tara, yet still make offerings to Tara at the end.
