Bhagavad Gita - Chapter 18, Verse 78

yatra yogeshvarah krishhno yatra paartho dhanurdharah |
tatra shriirvijayo bhuutirdhruvaa niitir matirmama ||

Meaning: Wherever there is Krishna, the Lord of Yoga and the bow weilding Arjuna, there reign good fortune, victory, prosperity and justice. Such is my conviction.
