When one has awoken from Muladhara, one goes into the water, which represents the unconscious where one faces the Leviathan/Crocodile from the depths which are ones own demons.
The Leviathan is the biggest and most fearsome creature of the watery depths.
(but it represents the same animal as the elephant, the one that supports your earthly life seems to become your worst enemy when you reach the next center, because here you leave this world and anything that hangs around is your worst enemy.
It is the water elephant, the whale that eats you, the same that has nurtured and supported you.
The good willing mother that raised you becomes a devouring one. When one dreams of baptizing, taking a batch, the ocean or in water generally – you must realize you are being pushed into the unconscious for purification, you have to go into the water because of the renewal.
But it remains unknown what comes after. When one passes through this baptizing, you reach Manipura.
