Sri Ramakrishna and Mother Sarada Devi were husband and wife when we look them from the point of view of society. Sexual relationship is an important part of husband and wife relationship. But the couple was above the carnal desires and lust. So here is a look at the sexual relationship between Sri Ramakrishna and Mother Sarada Devi.
One day while Mother Sarada Devi was massaging the Master’s feet (feet of Sri Ramakrishna Paramahamsa), she asked him, ‘How do you look upon me?’ Sri Ramakrishna replied: ‘The same Mother who is in the temple, the same Mother who gave birth to this body and is now living in the nahabat, that same Mother is now rubbing my feet. Truly, I always see you as a form of the blissful Divine Mother.’
One night as he watched Mother Sarada Devi lying asleep beside him, Sri Ramakrishna began to discriminate, addressing his own mind: ‘O my mind, this is the body of a woman. Men look on it as an object of great enjoyment and they always lust after it. But if one possesses this body, one must remain confined within the flesh; one can’t realize God. O my mind, let there be no theft [hypocrisy] in your inner chamber. Don’t be thinking one thing [inwardly] and pretending another outwardly! Be honest—do you want this woman’s body, or do you want God? If you want the body, here it is in front of you. Enjoy it.’
Discriminating in this way, the Master was about to touch Mother Sarada’s body when his mind suddenly recoiled and lost itself so deeply in samadhi that he did not regain normal consciousness all night. The next morning after considerable difficulty he was brought back to the conscious plane when Bhagavan’s name was repeated in his ear. (The Gospel of Sri Ramakrishna - 349, trans.
