Thousands sit in Vajrayogini contemplations every day and advance not an inch. Why is that?
First because there is not a full Confidence in the Dharma, and second because they cannot see beyond the words of the texts, the prostrations and the Visualizations to where the finger is pointing.
Sherab had a mind that was capable of seeing through the veils and, knowing the difficulty of the task, nonetheless set her feet upon the correct path.
We constructed together in the Seminary a real Vajrayogini Mandala, which covered an acre in which the mountains, barriers and gates were represented with real material and geographic elements.
No longer for her was there simply a graphical representation but a real-world Mandala which could be tackled with the visualizations and the alert mind.
We wrote a book, which one day perhaps will be available on Internet, which explains the process in detail.
Sherab stepped into that world and met with Heruka, but the final Union was denied, perhaps because she was not yet ready, or perhaps because the deeper understanding of that Union was too complex.
But the Dharma provides many doors and so she learned the Deeper significance of the Feminine and Masculine Principles and how the Union can be made.
Thus the final door was opened.
