To describe the form, somebody should have seen it in full. Has anybody seen it? # Of course it is not right to say that She has never been seen at all. Because we have several poet-devotees who have had a flash of Her and in the wake of that flash have composed wonderful devotional poetry.
Even in the case of the greatest of devotees, to whom She might have given darshan, maybe one got to see Her lotus feet, another the Graceful eyes, and another the bewitching smile in the face. Like that some part of Her may have caught the eyes of even these devotees; but never the full form!
