"If I can develop my mind completely, I become identified with Heaven," declared Lu Hsiang-shan (1139-1193). This exactly explains the message of philosophy to every man. No education which ignores this can therefore be called a full education, perhaps not even a true one.
Chou Tun-Yi wrote, "The way of the sage is nothing but love, righteousness, the Mean, and correctness. Preserve it, and it will be ennobling. Practise it, and it will be beneficial. Prolong it, and it will match Heaven and Earth. Is it not easy and simple? Is it hard to know? If so, it is because we do not preserve, practise, and prolong it."
