The heavenly realm is composed of gods and demigods—the good life, right? Eating ambrosia, eternal youth, every wish fulfilled. The gods live in beautiful palaces and have no cares. But this sweet life is also extremely dangerous to the spirit—the gods have little incentive to help others or enlighten themselves, because they live in ultimate comfort and luxury. The gods are isolated from real life and can struggle to understand the suffering of others. So when they die, and yes, gods can die, they risk a truly terrible series of rebirths—hell, hungry ghost, tapeworm, foot fungus, etc.—for all of the time they wasted.
Sound familiar? In many ways, our own world is filled with short-sighted citizens and leaders that have mismanaged their resources. The Wheel of Life reminds us not to grow complacent or ignorant of the suffering around us when we have the ability to change the world for the better.
