From the Bible:
In the Gospel of St. Luke, Chapter 15, we read the famous Parable of the Prodigal Son. Jesus tells of the man who took the wealth bestowed on him by his father, and squandered it in foreign lands, where he fell into evil ways. At last, repentant, he returned to his father’s home. When his father saw him, he was (Jesus tells us)
moved with compassion, and ran and fell upon his neck and kissed him. And the son said to him, “Father, I have sinned against heaven and before thee. I am no longer worthy to be called thy son.” But the father said to his servants, “Fetch quickly the best robe and put it on him, and give him a ring for his finger and sandals for his feet; and bring out the fattened calf and kill it, and let us eat and make merry; because this my son was dead, and has come to life again; he was lost, and is found.” And they began to make merry.
From the Bhagavad Gita, in the sixth Chapter:
Supreme blessedness is that yogi’s who has completely calmed his mind, controlled his ego-active tendencies (rajas), and purged himself of desire, thereby attaining oneness with Brahma, the Infinite Spirit.
