Our minds must be disciplined through our own study.

Our hearts' powers must be developed and trained through our own loving and doing.

One writes of two friends and two ways of showing friendship:-- "One brought a crystal goblet overfull Of water he had dipped from flowing streams That rose afar where I had never trod-- Too far for even my quickened eye to see.
They were fair heights, familiar to his feet-- They were cool springs that greeted him at morn, And made him fresh when noon was burning high, And sang to him when all the stars were out; His hand had led them forth, and their pure life Was husbanded, with sacred thrift, for flower, And bird, and beast, and man.

The hills were his, And his the bright, sweet water.

Not to me Came its renewal.
