Shapeshifting requires the ability to transcend your attachments, in particular your ego attachments to identity and who you are. If you can get over your attachment to labeling yourself and your cherishing of your identity, you can be virtually anybody. You can slip in and out of different shells, even different animal forms or deity forms.
The forms of the central and surrounding deities... should not be protruding like a clay statue or cast image, yet neither should they be flat like a painting. In contrast, they should be apparent, yet not truly existent, like a rainbow in the sky or the reflection of the moon in a lake. They should appear as though conjured up by a magician. Clear appearance involves fixing the mind one-pointedly on these forms with a sense of vividness, nakedness, lucidity, and clarity.
