There is only one constant. One entity. One God.
It is within this one entity that all exist, dreaming their non-existent individuality and discretion from the rest of the Universe.
As animals, we all crave purpose. It is an inherent illusion, built in to our system that enables out to carry out basic survival processes. It is the running of these processes that assists in creating that delusion of individual purpose.
And we need this, as biological machines, to function till death.
However, the grander truth of the matter is that we are all united in one Ultimate Purpose that no-one can know, no-one can see, and no-one can ever understand. That's because this purpose was never conceived to be understood by a human mind. Indeed, it is those very egoistic projections that "there must be a purpose!" that is perhaps the key limiting factor to our comprehension.
The fact is that there is no purpose. No goal. No Ultimate Resolution.
The Universe exists as a self-perpetuating mass, undying, self-existent. Like the mool mantra says.
But our emotions of good, evil, love and hate - all extrapolations of our inherent programming to simply survive - lead us to project those same human fallicies upon the greater Universe around us. It is why we have uilt stone statues of 'Gods', and why we refer to God as a 'He' instead of an 'It'. It is also why we spend hours on forums asking people what they think God's function in the Universe is and which religion 'has it right', if any. It is our own natures that limit us.
Someone once asked Stanley Kubrick if he felt the Universe was benevolent or evil. His response was that "the Universe is neither benevolent nor evil - it is merely indifferent".
