Morality, religion and politics are indispensable to achieve the end of general welfare, nation building and international peace. Ethics of Sri Aurobindo thought stands the test of time for its universal character. Sri Aurobindo makes the individual mediate on the millions of dispossessed. Human beings should think about the general human interests and misery instead of concentrating on their own selfish interests. He makes the individual discover truth by thinking of his neighbour, who represents humanity in miniature. In this context, Sri Aurobindo’s teaching and philosophy is of utmost importance if human beings want to live in peace and harmony. He is relevant in the twenty-first century where science and spirituality must go side by side. The scientific development which is putting value only in materialistic progress will not be able to achieve permanent peace in the world; simultaneously it is necessary to uplift human beings through spirituality. He emphasizes on spiritual freedom and spiritual oneness.
