श्रीमद् भगवद्गीता

मूल श्लोकः

बन्धुरात्माऽऽत्मनस्तस्य येनात्मैवात्मना जितः।

अनात्मनस्तु शत्रुत्वे वर्तेतात्मैव शत्रुवत्।।6.6।।

 

English Translation Of Sri Shankaracharya's Sanskrit Commentary By Swami Gambirananda

6.6 Tasya, of him; yena, by whom; jitah, has been conered, subdued; his eva atma, very self, the aggregate of body and organs; that atma, self; is bandhuh, the friend; atmanah, of his self. The idea is that he is a coneror of his senses. Tu, but; anatmanah, for one who has not conered his self, who has no self-control; atma eva, his self itself; varteta, acts; satruvat, like an enemy; satrutve, inimically, with the attitude of an enemy. As an enemy, who is different from oneself, does harm to oneself, similarly one's self behaves like an enemy to oneself. This is the meaning. [If the body and organs are under control, they are helpful in concentrating one's mind on the Self; but, if they are not under control, they oppose this concentration.]
