An insight has occurred to me from observing my pets.
Sometimes, the doggies lie at the kitchen door and stare longingly at the world through the windowpane. They can see happiness, freedom and sunshine outside. It seems to be right within their reach and yet something impenetrable is in their way, the nature of which they cannot comprehend. The mechanics of door opening is a deep mystery to them.
Aren't we all like them in a way? Our noses are also pressed against the closed door of illusion and ignorance. Beyond it we can clearly discern freedom, beauty, joy. And yet some inexplicable force is keeping the access blocked and we can only gaze wistfully at the richness of life through the windowpane of our mind.
