Are you any of those manufactured, luminous "Divine Bodies"?
Or are you really that which remains - primordial consciousness, that which permeates even empty space, the Absolute, the universal, the Logos.
Hindu sages call this Atman -- the "Self." Buddhist sages call it An-atman -- "No-self." The difference is just semantics. Both speak of the same primordial nature...)
Now, remaining in the awareness that YOU ARE THAT, come back to the visceral experience of your physical body, firmly planted in physical reality.
Your real self nature can be experienced here, too, in everyday existence, because It permeates all things.
Repeat the meditation as often as you like, to remind you of your own real Nature.
Remember, tantric visualizations are designed to shift awareness, emotional state, or physical sensation.
They can powerfully affect your physiology and awareness, especially when repeated often, so get a medical checkup before you make any life change, including beginning tantric visualization.
If you ever feel unwell, stop and contact your physician to determine if anything is wrong.
If your doctor finds no underlying medical cause, contact an experienced, realized meditation teacher for pointers.
If you are healthy but feel a little lightheaded or spacey, you can always stop and ground yourself for a bit...by walking, or massaging your hamstrings, your feet, or the nerve endings in your sacrum...
or simply visualizing yourself as a tree and breathing through roots extending deeply into the ground...http://spirithealers.blogspot.com/2013/04/grounding-should-be-practiced-at-least.html
if the feeling persists, call your physician just to be sure...
Smile, Breathe Right, and Keep Your Tongue Up!
