The 'whirlpool' (the revolving sky dome) has been described in the excursion at haati. I there referred to it while discussing the narrow hanga rave sign at Hanga Te Pau (cfr at Hatinga Te Kohe). It is here named Hvergelmir:

... Near the root which plunged into Niflhel, the underworld, gushed forth the fountain Hvergelmir, the bubbling source of the primitive rivers ...

The 'whirlpool' is the source of life, because it is the source of movement. Movement is life.

The hanau concept should therefore be closely associated with the 'whirlpool'. We have been there already, at the 'source of the rivers', in the maitaki 'chapter':

... Hast thou entered into the springs of the Sea? Or hast thou walked in the search of the depths? (Job XXXVIII. 16)

It will help now to take a quick comparative look at the different 'dialects' of mythical language as applied to 'Phaeton' in Greece and India. The Pythagoreans make Phaeton fall into Eridanus, burning part of its water, and glowing still at the time when the Argonauts passed by.

Ovid stated that since the fall the Nile hides its sources. Rigveda 9.73.3 says that the Great Varuna has hidden the ocean. The Mahabharata tells in its own style why the 'heavenly Ganga' had to be brought down. At the end of the Golden Age (Krita Yuga) a class of Asura who had fought against the 'gods' hid themselves in the ocean where the gods could not reach them, and planned to overthrow the government. So the gods implored Agastya (Canopus, alpha Carinae = Eridu) for help.

The great Rishi did as he was bidden, drank up the water of the ocean, and thus laid bare the enemies, who were then slain by the gods. But now, there was no ocean anymore! Implored by the gods to fill the sea again, the Holy One replied: 'That water in sooth hath been digested by me. Some other expedient, therefore, must be thought of by you, if ye desire to make endeavour to fill the ocean ...
