Below are paragraphs from the book "Brahmacharya by Shri Swami Sivananda Sarasvati"

"The love between husband and wife is mainly physical, selfish and hypocritical. It is not constant. It is of an ephemeral and changing nature. It is carnal passion only. It is sexual appetite. It is tinged with lower emotions. It is of bestial nature. It is finite. But divine love is infinite, pure, all-pervading and everlasting. There is no question of divorce here."

"As there is no real union in their heart of hearts, there is always some kind of friction and rupture, wry faces and hot words, in every house. If the husband does not take his wife to the cinema, there will be fighting in the house. Can you call this real love? It is mercenary, commercial business. On account of lust, men have lost their integrity, independence and dignity. They have become the slaves of women. What a pitiable spectacle you see!"

"In mercenary love, there cannot be any real happiness between the two, the lover and the beloved. If the husband is in a dying condition, the wife takes the bank passbook and walks to her mother’s house quietly. If the husband loses his job for some time, the wife shows wry faces, speaks harsh words and does not serve him properly with any love. This is selfish love. There is no real affection from the core of the heart. So there is always quarrel, fighting and Asanti in the house. Husbands and wives are not really united. They pull on anyhow, dragging a dreary, cheerless existence."

"A husband loves his wife not for the sake of his wife, but for the sake of his own self. He is selfish. He expects sensual pleasure from her. If leprosy or smallpox destroys her beauty, his love for her ceases. When the wife dies, the husband is drowned in sorrow, not because of the loss of his loving partner in life, but because he cannot get sexual pleasure now."
