If we affirm one moment, we thus affirm not only ourselves but all existence. For nothing is self-sufficient, neither in us ourselves nor in things; and if our soul has trembled with happiness and sounded like a harp string just once, all eternity was needed to produce this one event - and in this single moment of affirmation all eternity was called good, redeemed, justified, and affirmed.
The soul comes from without into the human body, as into a temporary abode, and it goes out of it anew it passes into other habitations, for the soul is immortal.
There is nothing more harmful to you than improving only your material, animal side of life. There is nothing more beneficial, both for you and for others, than activity directed to the improvement of your soul.
