Dnyaneshwar's moral philosophy comes out in his exposition of the 13th of "Bhagavad Gita", in his commentary on the book "Dnyaneshwari". He considers humility; non–injury in action, thought and words; forbearance in the face of adversity; dispassion towards sensory pleasures; purity of heart and mind; love of solitude and devotion towards one's Guru and God as virtues; and their corresponding moral opposites as vices. A pessimistic view of one's life is considered as a necessary condition for spiritual growth in "Dnyaneshwari". Dnyaneshwar writes that saints do not perceive distinctions and are humble because they identify all objects, animate or inanimate, with their own Self.
