Srimad Bhagavad-Gita :
Chapter-2. ( Samkya-yogam )
Slokam-60. (Hey Arjuna : The senses are so strong and impetuous, , that they forcibly carry away the mind even of a man of discrimination who is endeavoring to control them. )
Yatato hyapi kaunteya purushasya vipascitah,
Indriyanni pramathini haranti prasabham manah.
kaunteya! = hey Arjuna!
yatatah vipascitah = one who strive to control and regulate senses;
purushasya = and who have the knowledge of sastram-s;
manah api = in spite of these ( the above said capacity and efforts ) the mind;
pramathini indriyanni = highly stimulated senses;
prasabham haranti hi = certainly use force and throw away ( the mind ) violently.
Since it is not possible without controlling the senses to be one in steady wisdom; it is strongly recommended that in the practice of ones spiritual austerities one apply themselves diligently in this regard. The senses are so turbulent that they can forcibly take the mind of even a person of discrimination, for the senses are very agitating.
Even men of wisdom who lack spiritual experience and resort to using the mind as their only medium of understanding are soon overpowered by the senses. What then is the impediment to those who take pride in the bodily conception? Lord Krishna use of the word pramathini meaning turbulent indicates one who is assailed by agitation.
Until and unless self-realisation is attained by direct soul cognition the cravings and attachments for sensual experiences will never entirely cease to exist subtly or physically. The concerted exertions of even the persevering yogi can all be to no avail against the restless and powerful senses of which any one of them can forcibly decoy the mind astray. Thus the conquest of the senses is ultimately dependent upon realisation of the eternal soul and the perception of the soul is dependent upon control of the senses. Thus Lord Krishna alludes to the difficulty there is in striving for soul cognition following jnana-nishta by knowledge only.
Thus the control over the senses is root cause of stabilising the mind. Now Lord Krishna reveals the flaws in not possessing a stable mind. One situated in spiritual intelligence with discrimination and powers of observation trying their level best to keep the mind from gravitating towards the senses and withdrawing their mind repeatedly away from objects of the senses and directing it internally within is a form of meditation. But the senses are so strong that they forcibly invade the mind, disrupt this meditation and forcibly overpower the mind and indulge it in contemplating sense gratification and bodily attachment. How is it possible that the senses can carry away ones mind while they are intently striving? It is because the senses are so restless and turbulent that they totally disregarding all ones efforts in discrimination, besieging the mind they direct it towards sensual objects that will gratify these self-same senses by engaging the mind in sense contemplation.
