I no longer make an extensive use of the word "spirituality," as it somehow reinforces the illusion that it is some realm located somewhere else, rather than HERE and NOW.
It took me a long time to get to the simple realisation that the spiritual world is where we live, and the soul is who we are. And that all the different layers of reality are equally accessible to all of us at all times, depending merely on what we allow ourselves to perceive in any given moment.
And from this perspective birth & death are simply cyclic changes in the awareness of who we are, as we stretch ourselves towards infinity.
And we don't have to make it complicated. And it doesn't need to be a mysterious dogma anymore to embrace and appreciate the beauty of it.
It's just as simple as that, and each of us is entitled not only to believe it but to BE it and live it in this very moment. Without needing any further evidence.
