Acharya Prashant explains the profound meaning behind Kabir Saheb's words regarding the duality of crying and laughing. He states that crying is a sign of atheism because it stems from the belief that the Supreme is absent or that something essential has been lost. Since the Truth can never be lost, a mind that cries reveals its attachment to worldly objects and its distance from the source of true strength, which is the Self. Consequently, crying leads to a decrease in inner strength because the individual denies the very source of power.
