Bhagvad Gita, the prominent Hindu Scripture and one of the best illustrated ancient scriptures in the world, has several hundreds of Slokas. Eka Sloka Bhagvad Gita explains the whole Bhagvad Gita in one single verse.
Yathra Yogeswarah Krishno yathra Partho dhanurdarah
Tathra shirr vijayobhuthir dhruvaneethir mathirmama
‘Where there is Krishna, Yoga’s Lord,
and where there is Arjuna, the archer,
wealth, victory, prosperity and justice,
will be there; such is my conviction.’
