Hello Mut, I have not heard this phrase before, but from the 20th dynasty there was a rejuvination festival carried on at Medinet Habu on behalf of the king which implied the death and rebirth of the land thought to be connected to the kings symbolic death and rebirth.
At some stage during the festival the king would cut a sheaf of wheat symbolising the death of the wheat at harvest. Meanwhile the Queen, a personification of Isis, would parade around uttering spells and incantations to ensure her husbands rebirth. A white bull would be sacrificed, which symbolised the death of the king, its ears would be presented to the king and the tail would be paraded around to show to the people probably as a symbol of rebirth.
A sacred marriage ceremony would then be carried out by the king and queen with the king taking the part of Min and the queen as Isis, or maybe Hathor. At some point 4 birds would be released to carry the good news to the four points of the compass, and it may be from this that Habu became known as the center of life for this is where the rebirth ceremony of the king (and the land) took place. (at least during the time of Ramasses III 20th dynasty)
Hope this answers your question Mut Horus
