O Krishna, the stillness of divine union which you describe is beyond my comprehension. How can the mind, which is so restless, attain lasting peace? Krishna, the mind is restless, turbulent, powerful, violent; trying to control it is like trying to tame the wind. – Bhagavad Gita
Valor, glory, firmness, skill, generosity, steadiness in battle and ability to rule — these constitute the duty of a soldier. They flow from his own nature. – Bhagavad Gita
