बन्धुरात्मात्मनस्तस्य येनात्मैवात्मना जितः | अनात्मनस्तु शत्रुत्वे वर्तेतात्मैव शत्रुवत्
bandhurātmātmanastasya yenātmaivātmanā jitaḥ . anātmanastu śatrutve vartetātmaiva śatruvat
對於那些藉由真我（Atman）戰勝了自我的人，他們的真我（Atman）便是自我的朋友。但對於那些未能戰勝自我的人，他們的自我（低級心意）便會像敵人一樣，處於敵對狀態。
Of him, by whom has been conered his very self by the self, his self is the friend of his self. But, for one who has not conered his self, his self itself acts inimically like an enemy.
藉由高級心意戰勝低級心意。低級心意是你的敵人，高級心意是你的朋友。如果你與高級心意結交，你就能輕而易舉地制服低級心意。低級心意充滿了激性（Rajas）和惰性（Tamas，激情與黑暗），而高級心意則充滿了悅性（Sattva）或純淨。真我（Atman）是那些自制、並已制服低級心意和感官的人的朋友。但真我（Atman）是那些沒有自制力、沒有制服低級心意和感官的人的敵人。正如外在的敵人會傷害他一樣，他自己的（低級）自我（心意）也會傷害他。低級心意會嚴重傷害他。最高真我（Atman）是主要的真我。心意也是自我。這是次要的自我。
Coner the lower mind through the higher mind. The lower mind is your enemy. The higher mind is your friend. If you make friendship with the higher mind you can subdue the lower mind ite easily. The lower mind is filled with Rajas and Tamas (passion and darkness). The higher mind is filled with Sattva or purity.The Self is the friend of one who is selfcontrolled? and who has subjugated the lower mind and the senses. But the Self is an enemy of one who has no selfrestraint? and who has not subdued the lower mind and the senses. Just as an external enemy does harm to him? so also his own (lower) self (mind) does harm to him. The lower mind injures him severely. The highest Self or Atman is the primary Self. Mind also is self. This is the secondary self.
