द्यूतं छलयतामस्मि तेजस्तेजस्विनामहम्।जयोऽस्मि व्यवसायोऽस्मि सत्त्वं सत्त्ववतामहम्॥

dyūtaṁ chhalayatām asmi tejas tejasvinām aham jayo 'smi vyavasāyo 'smi sattvaṁ sattvavatām aham

I am the gambling of cheats. I am the splendor of the splendid. I am victory, I am determination, and I am the goodness of the virtuous.
