Sri Ramakrishna accepted the divinity of Buddha and used to point out the similarity of his teachings to those of the Upanishads. He also showed great respect for the Tirthankaras, who founded Jainism, and for the ten Gurus of Sikhism. But he did not speak of them as Divine Incarnations. He was heard to say that the Gurus of Sikhism were the reincarnations of King Janaka of ancient India. He kept in his room at Dakshineswar a small statue of Tirthankara Mahavira and a picture of Christ, before which incense was burnt morning and evening.

Without being formally initiated into their doctrines, Sri Ramakrishna thus realized the ideals of religions other than Hinduism. He did not need to follow any doctrine. All barriers were removed by his overwhelming love of God. So he became a Master who could speak with authority regarding the ideas and ideals of the various religions of the world. "I have practised", said he, "all religions Hinduism, Islam, Christianity and I have also followed the paths of the different Hindu sects. I have found that it is the same God toward whom all are directing their steps, though along different paths. You must try all beliefs and traverse all the different ways once. Wherever I look, I see men quarrelling in the name of religion Hindus, Mohammedans, Brahmos, Vaishnavas, and the rest. But they never reflect that He who is called Krishna is also called Siva, and bears the name of the Primal Energy, Jesus, and Allah as well the same Rama with a thousand names. A lake has several ghats. At one the Hindus take water in pitchers and call it 'jal'; at another the Mussalmans take water in leather bags and call it pani'. At a third the Christians call it 'water'. Can we imagine that it is not 'jal', but only 'pani' or 'water'? How ridiculous! The substance is One under different names, and everyone is seeking the same substance; only climate, temperament, and name create differences. Let each man follow his own path. If he sincerely and ardently wishes to know God, peace be unto him! He will surely realize Him."

In 1867 Sri Ramakrishna returned to Kamarpukur to recuperate from the effect of his austerities. The peaceful countryside, the simple and artless companions of his boyhood, and the pure air did him much good. The villagers were happy to get back their playful, frank, witty, kind-hearted, and truthful Gadadhar, though they did not fail to notice the great change that had come over him during his years in Calcutta. His wife, Sarada Devi, now fourteen years old, soon arrived at Kamarpukur. Her spiritual development was much beyond her age and she was able to understand immediately her husband's state of mind. She became eager to learn from him about God and to live with him as his attendant. The Master accepted her cheerfully both as his disciple and as his spiritual companion. Referring to the experiences of these few days, she once said: "I used to feel always as if a pitcher full of bliss were placed in my heart. The joy was indescribable."
