Here is a quote from metahistory.org where John describes what you can expect to get in dakini instruction based on his firsthand experience, and he prescribes how you can have such experience on your own.
"The presiding devata of a lunar cycle does not intervene and make things happen, nor does she direct or describe what you can expect to get in dakini instruction.
Her instruction comes in "the way a weathercaster would describe the meteological conditions of a storm front in which he navigates, and into which you are heading. I describe these effects.
Just follow the lunar cycle day by day and observe what arises in your mindstream. I have no technique to impart: all you have to do is pay attention. At the very most, the technique required here is to learn the character of these devatas and gear your attention to the phases of the lunar cycle: observe, attune, define, reflect and select, refine, complete.
If you want to receive dakini instruction from the Shakti Cluster recognize their traits, receive their frequencies. It's as simple as that.
Let me emphasize again that dakini instruction is always a rush, delivered in rapid and concise mentation. Subliminal thinking has a clean, preconceptual edge. It is not prolix, you do not ponder and muse and work it out. You just get it. You undergo sudden, dazzling flashes of insight. A single phrase or flicker of subliminal language, the twilight talk of the dakinis, can jolt you into a state of awakening that may last for several seconds, or minutes. Then you will lapse back into ordinary mentation, routine inner chatter. With practice, you can sustain and prolong the moments of insight. Get up to just fifteen minutes and you will find that the lucidity is almost unbearable. But so vivid, so clear and empty of mental dross, intoxicating like a lungful of ozone quaffed right out of a passing thunderstorm. Each of the Diamond Sky Dakinis in the pentad (Vajra Jewel) around VV teaches and emanates one of these unions, while VV herself informs and imparts the union of desire and appearance. The devatas of the Shakti Cluster hold you to your highest desire and entrain you with that desire toward liberation here and now."
The Shakti Cluster delivers. And how.
