इन्द्रियाणां हि चरतां यन्मनोऽनुविधीयते | तदस्य हरति प्रज्ञां वायुर्नावमिवाम्भसि || २ ६७ || indriyaaNaam hi charataam yan-mano ‘nuvidhiiyate tadasya harati pragnyaam vaayur-naava-mivaam-bhasi (SBG 2:67) Just the way a strong wind moves a ship sailing on the water away from its course, any of the senses that the mind follows and concentrates on, can lead astray the wisdom of a person. (SBG 2:67)
नास्ति बुद्धिरयुक्तस्य न चायुक्तस्य भावना | न चाभावयतः शान्तिरशान्तस्य कुतः सुखम् || २ ६६ || naasti buddhi-rayuk-tasya na chaayuk-tasya bhaavanaa na chaabhaa-vayataha shaantir- ashaantasya kutah sukham (SBG 2:66) There cannot be spiritual knowledge and intelligence in a person who is devoid of meditation. Such a person, without a mind which is fixed has no peace. How can a person with no peace find happiness? (SBG 2:66)
प्रसादे सर्वदुःखानां हानिरस्योपजायते | प्रसन्नचेतसो ह्याशु बुद्धिः पर्यवतिष्ठते || २ ६५ || prasaade sarva-duhkhaanaam haani-rasyo-pajaayate prasanna-chetaso hyaashu buddhih parya-vathisht-hathe (SBG 2:65) When serenity of mind through Divine Consciousness is achieved, all material miseries are destroyed and the intellect of such a person is steady. (SBG 2:65)
But the person who controls his senses, in spite of being with sense objects, is free from both attachment and aversion. Such a person attains a state of serenity. (SBG 2:64)
A person who thinks of sense objects develops an attachment to them. From this attachment, desires are born, and from desires, anger is born. (SBG 2:62)
क्रोधाद्भवति संमोहः संमोहात्स्मृतिविभ्रमः | स्मृतिभ्रंशाद् बुद्धिनाशो बुद्धिनाशात्प्रणश्यति || २ ६३ || krodhaad bhavati sammohaha sammohaat smrti vibhramaha smrti bhramshaad buddhi naasho buddhi naashaat praNashyati (SBG 2:63)
Anger gives birth to delusion, and this delusion results in confusion of memory. When memory is confused, intelligence is destroyed and from the destruction of intelligence, the person perishes. (SBG 2:63)
O son of Kunti, the senses are so strong and turbulent, that they can forcibly lead astray the mind of even a wise person who is striving hard to control them. (SBG 2:60}
He who is not agitated or disturbed amidst difficulties; is also not euphoric when he has comforts and is free from attachment, fear and anger; is known to be a sage with a steady mind. (SBG 2:56)
