बन्धुरात्मात्मनस्तस्य येनात्मैवात्मना जितः । अनात्मनस्तु शत्रुत्वे वर्तेतात्मैव शत्रुवत् ॥ ६ ॥
bandhur ātmātmanas tasya yenātmaivātmanā jitaḥ anātmanas tu śhatrutve vartetātmaiva śhatru-vat
Translation
For one who has conquered the self by the self, the self is a friend; but for one who has not, the self behaves like an enemy.
Hindi Meaning (हिंदी अर्थ)
जिसने मन को अपने आप से जीत लिया है, उसके लिए उसका मन मित्र है; और जिसने मन को नहीं जीता, उसके लिए वह स्वयं शत्रु के समान बर्ताव करता है।
Commentary
Continuing 6.5, this verse says our own mind can be our best friend or worst enemy. The difference is whether we have trained it. No outside enemy can harm us as much as an undisciplined mind.
