Body Satva - The Ultimate Ideal

Buddha thought to himself, he had so much love for his wife and for his newborn child. But how could he protect them from these inevitable consequences of embodied existence? So, he left his status as a prince and he went out as a wandering monk looking for a way to put an end to suffering. And eventually, every all know, he got enlightened and everything. And he taught others, he helped to save so many others. It's the ultimate ideal, why didn't Buddha remain as a body of satva? Why did he go for full extent and become enlightened?"
