I Am Confused Over The Benefit Of Having A Chaste Wife

“King Puranjana then began to think of his past dealings with his wife. He recalled that his wife would not take her dinner until he had finished his, that she would not take her bath until he had finished his, and that she was always very much attached to him, so much so that if he would sometimes become angry and chastise her, she would simply remain silent and tolerate his misbehavior.” (Shrimad Bhagavatam, 4.28.19)
