When you are sorrowful look again in your heart, and you shall see that in truth you are weeping for that which has been your delight. Some of you say, "Joy is greater than sorrow," and others say, "Nay, sorrow is the greater." But I say unto you, they are inseparable. Together they come, and when one sits alone with you at your board, remember that the other is asleep upon your bed. Verily you are suspended like scales between your sorrow and your joy.
Joie est mon caractere, C'est la faute a Voltaire; Misere est mon trousseau C'est la faute a Rousseau. [Joy is my character, 'Tis the fault of Voltaire; Misery is my trousseau 'Tis the fault of Rousseau.] - Gavroche
Whatever suffering there is in this world,all arises from desiring only myself to be happy.And whatever joy there is in this world,all arises from desiring to share my happiness with everyone.
Life does not require you to sacrifice or compromise your joy to get what you want. Joy is what you want, so when you choose in harmony with it, you are fulfilling your purpose in living.
But that had been grief--this was joy. Yet that grief and this joy were alike outside all the ordinary conditions of life; they were loopholes, as it were, in that ordinary life through which there came glimpses of something sublime. And in the contemplation of this sublime something the soul was exalted to inconceivable heights of which it had before had no conception, while reason lagged behind, unable to keep up with it.
