Paramahansa Yogananda once said of the Thanksgiving holiday, "Be grateful of the Divine plan that will expedite the karmas of all the sacrificed turkeys, and be grateful that you are not one of the turkeys on the table."
and from Sri Dharma Mittra:
“God is right there in the center of your chest. This is our spiritual heart. The stomach residing underneath the heart center is the Lord’s Table. Practice ahimsa [no-harming], and consider what you are about to offer to the Lord, as your own body is his altar. As you sit to the feast, practice aparigraha [non-hoarding] and take only what you need and share equally with others. As we continue to practice yama & niyama [the ethical roots] and rest our mind on God, we will become more compassionate and our bodies will be cleansed physically, emotionally and spiritually. Our heart centers will become clearer and we will be lighter.”
