No team of scientists anywhere has yet invented anything as amazing as the simplest green creation of God. But rather than admit the existence of a superior intelligence, scientists mislead the public with their theories of chemical evolution, Without substantial evidence, they proclaim that life comes from chemicals. Yet they cannot utilize those chemicals to make a seed that will grow into a shaft of wheat that will produce more seeds that will sprout into hundreds of more shafts of wheat. Once we admit that life comes only from life, it's entirely reasonable to suppose that all life originates from a common living source, the one Supreme Lord, known to the Muslims as Allah, to the Jews as Yahweh, to the Christians as Jehovah, and to the followers of the Vedas as Krishna. So at the very least we should offer our food to God out of gratitude.
Every religion has such a process of thanks-giving.
But the spiritual path outlined in the Vedic scriptures of India is unique in that the offering of food to the Lord is part of a highly developed form of yoga that helps one develop one's personal loving relationship with God. This is called bhakti-yoga. Originally, each soul has a direct relationship with God in the spiritual world, and according to the Vedas the main purpose of life is to revive this lost relationship. Therefore every living entity, especially in the human form of life, must engage in devotional service. Devotional service, or bhakti-yoga, is the highest form of yoga.
