Symbols - What does heaven look like
A little creature that can survive and thrive in both Water and on the Earth. Furthermore it lays Eggs and can make a strange croaking noise. In many eastern systems a frog thus symbolises an initiate - a person at the start of the spiritual path who has not yet learnt to fly or sing, but paddles around between the spirit world and the physical world possibly going out of body, but basically learning. There is by implication a strong link with the physical world - the temptations of the physical are very strong still.
