You have the right to work, but never to the fruit of work. You should never engage in action for the sake of reward, nor should you long for inaction. Perform work in this world, Arjuna, as a man established within himself – without selfish attachments, and alike in success and defeat. ~ Bhagavad Gita

The wise grieve neither for the living nor for the dead. There was never a time when you and I and all the kings gathered here have not existed and nor will there be a time when we will cease to exist. ~ Bhagavad Gita

The nonpermanent appearance of happiness and distress, and their disappearance in due course, are like the appearance and disappearance of winter and summer seasons.They arise from sense perception,and one must learn to tolerate them without being disturbed. ~ Bhagavad Gita
