2:60 "The restless violence of the senses impetuously carries away the mind of even a wise man striving towards perfection."
So much is said in one little sentence! Sense themselves can be violent, and lead the mind astray. Even the man striving for perfection is at their mercy. In one way, it is a caution. In another, it says that we not uniquely at risk of succumbing to our senses.
2:61 "Bringing them all into the harmony of recollection, let him sit in devotion and union, his soul finding rest in me. For when his senses are in harmony, then his is a serene wisdom."
This is a very important verse to the Krishna conciousness movement. Swami Prabudhapa, the founder of the Hare Krishna movement (International Society for Krishna Consciousness or ISKC) translates it: "One who restrains his senses, keeping them under full control, and fixes his consciousness upon Me, is known as a man of steady intelligence." In the verse, Krishna is saying that sitting in devotion and fixing the mind on Him will help bring about harmony of the senses. It is interesting to note that Mascaro uses the term wisdom where Prabudhapa uses intelligence.
This is also more generally a verse supporting Bhakti, or devotional yoga.
But Krishna does not stop at defining the yoga of devotion. Over the next few verses, he give practical instructions.
2:62 "When a man dwells o the pleasures of sense, attraction for them arises in him. From attraction arises desire, the lust of posession, and this leads to passion, anger."
2:63 " From passion comes confusion of mind, then loss of remembrance, the forgetting of duty. From this loss comes the ruin of reason, and the ruin of reason leads man to destruction."
See the Second Noble truth: the root cause of suffering is desire.
2:64 ""But the soul that moves in the world of the senses and yet keeps the senses in harmony, free from attraction and aversion, finds rest in quietness."
The third Noble Truth: the end of suffering. Suffering ceases when a man rids himself of desires.
Neither Buddhist doctrine nor the verses here are advocating ridding oneself of senses or avoiding them by retreating from the world. It is desire that is faulted.
2:65 "In this quietness falls down the burden of all her sorrows, for when the heart has found quietness, wisdom has also found peace."
