The mantra "I am not the body, I am not even the mind" directly corresponds to moving through 1D - 2D for every time you repeat it. "Isha kriya" can be translated as "source of creation, inner process", where the 0D is the source of creation, so it matches up really well here. Each repeat of the mantra will take you 0D-1D-2D and then the breathing "aah" will push the energy from the bottom chakras through the body after you finish that part. Ending with the 3rd eye chakra focus is just standard practice and makes the effect better.
