Six in the third place means

He dissolves his self. No remorse.

Under certain circumstances, a man's work may become so difficult that he can no longer think of himself. He must set aside all personal desires and disperse whatever the self gathers about it to serve as a barrier against others. Only on the basis of a great renunciation can he obtain the strength for great achievements. By setting his goal in a great task outside himself, he can attain this standpoint.
