मनु-उपदेशः — भूत-उत्पत्ति, इन्द्रिय-निवृत्ति, तथा पर-स्वभाव-विवेकः
Manu’s Instruction on Elemental Origination, Sense-Withdrawal, and Discrimination of the Supreme Nature
इतीमं॑ हृदयग्रन्थिं बुद्धिभेदमयं दृढम् । विमुच्य सुखमासीत न शोचेच्छिन्नसंशय:,बुद्धिके द्वारा कल्पित हुआ जो भेद है, वही --हृदयकी सुदृढ़ गाँठ है। उसे खोलकर संशयरहित हो ज्ञानवान् पुरुष सुखसे रहे, कदापि शोक न करे
itīmaṁ hṛdayagranthiṁ buddhibhedamayaṁ dṛḍham | vimucya sukham āsīta na śocec chinnasaṁśayaḥ ||
Thus, this firm knot of the heart—made of the mind’s own manufactured divisions—should be untied. Having released it, the wise person should dwell in ease; with doubt cut away, he does not grieve.
भीष्म उवाच
Suffering and grief persist as long as the heart remains tied by rigid inner divisions fabricated by the intellect (seeing ‘I vs. other’, ‘mine vs. not-mine’, ‘gain vs. loss’). By loosening this knot through clear understanding, one becomes free of doubt and therefore free of grief, abiding in inner ease.
Bhishma, instructing on peace and right conduct in the Shanti Parva, concludes a point of spiritual counsel: the listener should untie the deep inner knot created by mental discrimination and thereby live calmly, with doubts resolved and sorrow ended.
