śhatrum

एवं बुद्धेः परं बुद्ध्वा संस्तभ्यात्मानमात्मना

śhatrum — the enemy

Knowing that which is beyond the understanding, steadying the lower self by the higher, strike down this enemy, mighty-armed one — desire, so hard to master.

बन्धुरात्माऽऽत्मनस्तस्य येनात्मैवात्मना जितः

śhatrutve — for an enemy

The self is a friend to the one who has mastered it; but for one who has not, the self remains hostile, like an enemy.

असौ मया हतः शत्रुर्हनिष्ये चापरानपि

śhatruḥ — enemy

That enemy I have killed, and I shall kill the others too. I am the lord, I am the enjoyer, I am successful, strong and happy.
