It is not through uniformity that you obtain unity.
It is not through uniformity of programmes and methods that you will obtain the unity of education.
Unity is obtained through a constant reference, silent or expressed, as the case demands, to the central ideal, the central force or light, the purpose and the goal of our education. The true, the supreme Unity expresses itself in diversity. It is mental logic that demands sameness. In practice, each one must find and apply his own method, that which he understands and feels. It is only in this way that education can be effective.
