Would you please telling me about the symbol of transformation in Judaism? By transformation, I meant the upgrade from something earthy, lower in nature to higher, or even sacred entities.
Here are similar examples in the Eastern tradition: a carp can become a dragon when it has the courage to jump over the "dragon gate" located at the top of the water fall in a sacred mountain. Or if a tiger lives up to 500 years, it turns white, and thus becomes a sacred animal, who guards the West, and and has the spirit of metal.
