TRANSLATION
One who is not in transcendental consciousness can have neither a controlled mind nor steady intelligence, without which there is no possibility of peace. And how can there be any happiness without peace?
Both ataraxia and the Vedic concept of inner peace (Shanti) highlight the importance of a serene and controlled state of mind: ataraxia seeks the absence of emotional disturbance, while the Vedas emphasize that true peace and happiness can only be achieved through a connection with transcendental consciousness.
