A wise person is one who looks into himself and finds out his own mistakes and faults, but the one who finds faults in others; he can neither knows himself what he really is; nor what his faults are. (SSVahini, p. 38)

When you consider all the pairs of opposites, such as joy and sorrow, heat and cold, profit and loss, honor and dishonor, with an equal mind, and are established in your true reality, then you have gained the characteristics of a wise man. It is the nature of the wise to treat everything equally. Once you recognize the nature of the senses, it will be easy for you to follow the path that leads to true wisdom. But if instead of identifying yourself with the atma, you continue to identify yourself only with your body-mind complex, then it will be impossible for you to obtain that exalted state. (SBGita)
