What is meant by the Perfect Reward-body? One light can illuminate the darkness of a thousand years, and one bit of wisdom can destroy the ignorance of ten thousand years. Never mind looking back to the past; always consider the future, and always make future thoughts good. This is called the Reward-body. The reward of one evil thought will remove the good of a thousand years, and the reward of one good thought will destroy the evil of a thousand years. At all times make the next thought a good one. This is called the Reward-body.
