Why the Sun?
Because the Sun likes to play hide-and-seek. But, since it shines so brightly and burns too hot for others to come very close to it, it has nobody but itself to play. So, in order to overcome this, it must pretend it is not itself. But how does it do this?
The Sun dreams.
It dreams that it is each and every being in the universe; the stars, the stones, the animals (including humans), and the plants. In the Sun's dreams it has many wonderful adventures. It likes it so well, that it sometimes cannot recall where and how it hid itself. But, that's also just what it wants to do - for if it found itself to quickly, the game would surely end.
That is why it is hard for us to find it; the Sun is hiding itself in us.
In this game of hide-and-seek, the Sun always finds it fun to find new ways of hiding, and to seek for someone who doesn’t always hide in the same place.
However, if it went on and on forever, it would get very tired of itself. Therefor, there are times when the Sun is, and then there are times when it is not. It is like one's breath - in and out, in and out. If one tries to hold it in all the time, one would feel terrible.
Eventually, the game is over, all of us will wake up and remember that we are all one single Sun - the One that is all and lives forever and ever.
Just like a circle.
And as the Sun goes around like a circle, there will be no particular place where it 'begins.' There is night as there is day; there is waking as there is sleeping; there is living as there is dying; there is summer as there is winter. You cannot have any one of these without the other - for what is darkness unless you had seen it side by side with light, or light unless side by side with darkness? As a circle, it moves from an inner dynamic of cyclical patterns as it carries forth the four seasons in its yearly round. Within this web of relationships and change, [i]its entity can be defined only by its function, and its significance only as part of the whole pattern.[/i] Likewise, all of life goes through the four stages of birth, maturation, decline, and death.
The Sun is also the Self of the world, but it is too 'bright' to directly be seen - and that is for the similar reason that one requires a mirror to see one's own self. This is why many dominating religions are dogmatic and divisive, for they depend on swapping this view for one that separates the believers from the heretics - even though we are all cut from the same cloth. Their institutions demand loyalty to their cherry-picked definitions of 'purity.' Furthermore, no 'creator' would wreck the human mind by making it so rigid and unadaptive such as the ones who depend on any one book, such as the bible, for all of *the* answers.
Words can only, at best, point beyond themselves to a world of life and death and experiences that are so much more than words in and of themselves.
