Stupas are hemispheric central structures, graves, with three parasols one above the other, representing the three worlds, namely:
dharmakâya (i.e., the purely spiritual world, the world of absolute truth), sambhoga kâya (i.e., the intermediate world, the world of subtle bodies) and the nirvana kâya (i.e., the world of objects, the world of created things).
One could also describe the three as Self, anima and body. ~Carl Jung, Psychology of Yoga and Meditation, Page 52
Tantra means book, a leaf of paper or weaving loom.
It is used for educational books or text books utilized for this special purpose. In its whole style Tantrism corresponds to the scholasticism of our Western culture.

The image was part of a greater number Jung collected, which he presented in his seminar series in Berlin in 1933. ~Carl Jung, Psychology of Yoga and Meditation, Page 57 Image 94
the âtman is the absolute origin of being.
The particular: that he is not only the universal being like that of the highest Buddha, the essence of the world itself, but he is also a personal being. Everyone has a personal Self, this âtman within, but this is only one aspect of the universal.
Whoever immerses himself in the practice of yoga, flows in a way out of the personal âtman into the general, and then considers himself a universal being. ~Carl Jung, Psychology of Yoga and Meditation, Page 62
