(1) When you are centered upon yourself as the Vajrayogini, perceiving your body, speech and mind to be actually Her body, speech and mind, your focus is already at the central channel.
(2) What you need to do now is just see the phenomena Source by looking directly at it in front of your eyes at first and then within the Heart.
(3) See what is going on: there is the One Source in the Heart which is the base of everything, and at the same time, there is phenomena manifesting from that One Source.
(4) You can see that there is letter BAM present at the core of the Source and as the phenomena ae well.
(5) Just breathe in as all the winds enter and dissolve in the central channel at the Heart and see that the BAM source is Vajrayogini Herself, which in turn is your own mind.
(6) But the Source and phenomena are always the same. There is the Mahayogini, the embodiment of wisdom of all the Buddhas of ten directions and three times, the Krodhakali, the emanation of complete Buddhahood in a female form, the one Vajrayogini.
(7) And She is full of complete absence of inherent existence and all other qualities – Herself as the combination of bliss and emptiness.
(8) There is no you and no Her, only vast and empty absence of presence that is the Source and phenomena simultaneously - nothing is separate from the central channel.
(9) As you breathe in you directly look at that absence of presence and see neither Her nor yourself nor your Gurudev, only thusness, even, non-arising and non-abiding, blissfully empty.
(10) There is no gain, no gain in the attainment of the natural thusness.
(11) As you breathe out you again clearly see yourself as Vajrayogini in the Outer Dakini Land, your Keajra Pure Land and, full of unlimited, boundless and unconditioned compassion, you utter the simple root essence mantra.
(12) This mantra embodies all the qualities of every other mantra in existence.
(13) Just by remembering it, even without repeating it and certainly without visualizing anything in particular, this mantra yields combined benefits, wisdom and merit of the trillions of dedicated repetitions of the Vajrasattva mantra, Offering Cloud mantra, Your root, heart and close heart mantras, the Heruka root, heart and close heart mantrs, the three Om mantra and the Eight lines prayer to Heruka and to Yourself, Vajrayogini.
(14) Out of spontaneous compassion you see that for this simple mantra there is no need for any formal and elaborate ritualistic practice.
(15) The final phase of the Vajrayogini completion sadhana is where it shines brightly, for all will have reached the end of what can be taught and meditated upon.
(16) Without a doubt, everyone who even only one time remembers this simple mantra will attain the Keajra Pure Land and the stage of No-more-Learning in this body and in this life, and thus contribute to all sentient beings on all levels of existence in innumerable compassionate ways.
(17) You see with full honesty that this is really true and utter the simple mantra for the benefit of all sentient beings.
(18) Om Ah Hrim... [full mantra withheld]
