Feeling alone is what most likely sparked this way of thinking. Realizing that everyone (consciously or subconsciously) feels alone too - but no matter what, we're actually ALL together - is what has helped evolve my way of thinking about it. Life feels less lonely, and that's a big obstacle to overcome.
Beloved, let your eyes half close, and your heart beat
Over my heart, and your hair fall over my breast,
Drowning love's lonely hour in deep twilight of rest.
My heart, the bird of the wilderness, has found its sky in your eyes. They are the cradle of the morning, they are the kingdom of the stars. My songs are lost in their depths. Let me but soar in that sky, in its lonely immensity. Let me but cleave its clouds and spread wings in its sunshine.
There is no God, no universe, no human race, no earthly life, no heaven, no hell. It is all a dream, a grotesque and foolish dream. Nothing exists but you. And you are but a thought -a vagrant thought, a useless thought, a homeless thought, wandering forlorn among the empty eternities!
