Visualize Vajrayogini on the crown of your head and yourself as Vajrayogini, with a hollow tube running from the secret organ up to the crown. At your heart, the size of a mustard seed, visualize yourself as Vajrayogini.

Then visualize a very fine thread of red light going from Vajrayogini on the crown of your head down to Vajrayogini in the mustard seed [at your heart.]

That red light hooks Vajrayogini in the mustard seed, and Vajrayogini comes up, which immediately brings you up into the heart of Vajrayogini [on your crown.]

Then you hear all the dakinis and dakas doing prayers and songs, and you meditate on bliss and voidness.
