Maʽat stands for the ancient concepts of truth, balance, order, harmony, law, morality, and justice.
Ma’at was the Egyptian goddess who personified these concepts, and regulated the stars, seasons, and the actions of mortals and deities who brought order from chaos at the moment of creation. The name of our Fund reflects the influence of the concepts of Ma’at on our values. Our activities aspire to demonstrate an understanding that our actions in life affect not only ourselves, but others’ lives as well – the principles of harmony and balance.
