Even today if we can do the japas and dhyAnas in the proper manner, and melt our hearts in intense devotion, those forms can be seen as we see each other in the outside world. And when such divine sights occur our ordinary views of each other would pale into insignificance. The Love and Bliss that such sights generate will take us to the realisation of the Ultimate. Therefore it is not right to say that everything is an allegory.
To get back to what I was saying earlier, these divine forms which personify esoteric fundamentals, might contradict what we consider to be normal, right, decent, and beautiful in the ordinary mundane world. Just because of that it is not correct to conclude that the original reality itself is not right, decent and beautiful.
