When we pay respect to an image of the Buddha, we are not worshipping him. We respect the image as a representation of our Original Teacher and therefore we pay our debt of gratitude to him. This is why the followers of the Buddha respect the Buddha's images as well as memorial tablets of ancestors. This practice has a far-reaching and widespread educational significance, for at the sight of them, we remember our obligation of caring for and respecting our parents, teachers and elders. Earth Treasure Sutra tells us about compassion after explaining the Great Perfection.
Compassion is the third principle of the First Condition.
Compassion is also a virtue of self-nature and crucial to our practice. When the virtue of filial piety and respect for parents and teachers is expanded, it becomes compassion. Compassion includes not killing any living being. This statement has profound meanings. Without a thorough comprehension of the Earth Treasure Sutra, we cannot understand the true meaning behind not killing any living being.
