The student should concentrate on his heart, imagining that in his heart there is thunder and lightning, flowing clouds that get lost in the twilight driven by strong hurricanes. The gnostic will imagine many eagles flying throughout this infinite space which is deep, very deep within his heart. Imagine the profound forests of Nature, full of sunshine and life; the song of birds and the sweet and gentle sound of forest crickets. The disciple should fall asleep imagining all of this.
Now imagine that in the forest there is a golden throne where the Goddess Kakini sits, a very divine woman. The disciple should fall asleep imagining all of this.
Practice for one hour daily, and if you practice for two or three or four hours a day it is even better. The practice can be done sitting in comfortable chair or lying down on the floor, or on the bed, with his legs and arms open to the left and to the right in the form of a five-pointed star.
Sleep should be combined with meditation. Much patience is required. It is with infinite patience that these wonderful powers of the heart can be obtained.
