Bhagavad Gita 16.14
I have slain one enemy; I will slay the others too. I am worthy of enjoying; I am the Almighty, perfect, powerful, and happy.
असौ मया हतः शत्रुर्हनिष्ये चापरानपि।ईश्वरोऽहमहं भोगी सिद्धोऽहं बलवान्सुखी॥asau mayā hataḥ śatrurhaniṣye cāparānapi|īśvaro'hamahaṃ bhogī siddho'haṃ balavānsukhī||
