Unless he puts his abstract principles into concrete deeds, unless his highest thoughts are reflected in his lowliest acts, the student is no philosopher. These teachings have not been easy to comprehend in theory; they will certainly be still less easy to follow in practice. Nevertheless these rarefied principles must be translated into terms of everyday living. The skeleton must now be fleshed out and the warm living blood of action must course around it. Hence the third path seeks to connect this knowledge with the practical obligations of mundane existence and to associate these practices with the social and personal responsibilities of men who lead active lives.
