The Crux of the matter refers usually to the heart of the matter, its core. The basis of anything. When you head to the crux of anything, you are very likely to find a positive outcome, i.e. a solution. That is because you choose to begin in the right place, which is at the beginning. It can be productive to start elsewhere – like half-way between the problem and the solution – but a solution does not usually present itself to those who use short-cuts.
The Crux is also the other name for The Southern Cross, visible with the naked eye on clear nights in southern skies. It has been guiding sailors – and natives – for just about ever. It is important that you have The actual Crux when you start your search, or when you look to the sky for guidance. There is another cross – The False Cross – in the universal soup. You do not want to be reading directions from that.
It would seem that although ‘crux’ stems from Latin, it has travelled, too, via the Scandinavians and other interpreters of the time. Therefore it has different meanings, depending on why it is used, and by whom. In a literal sense for Christians, a ‘crux’, or ‘cross’, is a stark reminder of where Jesus ended his days. To someone other than that, it is not. It is reminiscent of a kiss in the night sky.
