क्रोधाद्भवति संमोहः संमोहात्स्मृतिविभ्रमः।
स्मृतिभ्रंशाद् बुद्धिनाशो बुद्धिनाशात्प्रणश्यति।।2.63।।
।।2.63।। क्रोध से उत्पन्न होता है मोह और मोह से स्मृति विभ्रम। स्मृति के भ्रमित होने पर बुद्धि का नाश होता है और बुद्धि के नाश होने से वह मनुष्य नष्ट हो जाता है।।
Lord Krishna is explaining that one whose cravings for sensual objects linger, the effort to overcome the senses without focusing the mind on the Supreme Lord is futile. This is due to the fact that without the Supreme Lords grace the residue of past sensual activities and the pleasure or frustration derived therefrom will delude the mind to pursue sense objects. This debilitating effect creates a magnetic attraction where the desire for sense objects becomes more and more extreme. From this extreme desire springs kama lust. Lust is the next stage of desire. Lust is that which one feels when they thinks that they cannot exist without their desire being gratified. From lust springs krodha anger. Krodha is that frustrated outraged one feels against that which stands in the way of obtaining the gratification of ones senses. From krodha arises sammoha bewilderment and delusion which is the mental condition where one is no longer cognisant of what action should be performed and what action should not be performed. One will foolishly do anything in this condition. Thereafter comes dementia causing loss in memory of the process one began in order to constrain the senses and control the mind. From dementia comes loss of will power, one no longer has the drive and incentive to cultivate themselves towards obtaining spiritual realisation of the eternal soul. When this happens then one perishes their spiritual opportunity being drowned again and again in samsara the endless cycle of birth and death in the material existence.
