The free soul has brought his thought and actions into perfect harmony with Nature's morality. He lives not merely for himself alone, but for himself as a part of the whole scheme. Consequently, he does not injure others but only benefits them. He does not neglect his own benefit, however, but makes the two work together. His activities are devoted to fulfilling the duties and responsibilities set for him by his best wisdom, by his higher self.
The world is necessarily affected by his presence and activities, and affected beneficially. First, the mere knowledge that such a man exists helps others to continue with their efforts at self-improvement, for they know then that the spiritual quest is not a vain dream but a practicable affair. Second, he influences those he meets to live better lives--whether they be few or many, influential or obscure. Third, he leaves behind a concentration of spiritual forces which works on for a long time, through other persons, after he leaves this world. Fourth, if he is a sage and balanced, he will always do something of a practical nature for the uplift of humanity instead of merely squatting in an ashram.
