Bhagavad-gītā As It Is · Text 7.11
Krishna as the source of all things
बलं बलवतां चाहं कामरागविवर्जितम् ।
धर्माविरुद्धो भूतेषु कामोऽस्मि भरतर्षभ ॥ ११ ॥
balaṁ balavatāṁ cāhaṁ
kāma-rāga-vivarjitam
dharmāviruddho bhūteṣu
kāmo ’smi bharatarṣabha
I am the strength of the strong, devoid of passion and desire. I am sex life which is not contrary to religious principles, O lord of the Bhāratas [Arjuna].
