“All will certainly realize God if they are earnest and sincere.”

Source: The Gospel of Sri Ramakrishna (1942), p. 423
Context: Truth is one; only It is called by different names. All people are seeking the same Truth; the variance is due to climate, temperament, and name. A lake has many ghats. From one ghat the Hindus take water in jars and call it "jal". From another ghat the Mussalmāns take water in leather bags and call it "pāni". From a third the Christians take the same thing and call it "water". Suppose someone says that the thing is not "jal" but "pāni", or that it is not "pāni" but "water", or that it is not "water" but "jal", It would indeed be ridiculous. But this very thing is at the root of the friction among sects, their misunderstandings and quarrels. This is why people injure and kill one another, and shed blood, in the name of religion. But this is not good. Everyone is going toward God. They will all realize Him if they have sincerity and longing of heart.

Context: The duties of a Prince Ameth are, to be earnest, true, reliable, And sincere; to protect the people against illegal impositions and exactions; to contend for their political rights, and to see, as far as he may or can, that those bear the burdens who reap the benefits of the Government.
You are to be true unto all men.
You are to be frank and sincere in all things.
You are to be earnest in doing whatever it is your duty to do.
And no man must repent that he has relied upon your resolve, your profession, or your word.
The great distinguishing characteristic of a Mason is sympathy with his kind. He recognizes in the human race one great family, all connected with himself by those invisible links, and that mighty net-work of circumstance, forged and woven by God.

Confessions Of A Sceptic
The Nemesis of Faith (1849)
Context: It was brought home to me that two men may be as sincere, as earnest, as faithful, as uncompromising, and yet hold opinions far asunder as the poles. I have before said that I think the moment of this conviction is the most perilous crisis of our lives; for myself, it threw me at once on my own responsibility, and obliged me to look for myself at what men said, instead of simply accepting all because they said it. I begin to look about me to listen to what had to be said on many sides of the question, and try, as far as I could, to give it all fair hearing.

Context: All will surely realize God. All will be liberated. It may be that some get their meal in the morning, some at noon, and some in the evening; but none will go without food. All, without any exception, will certainly know their real Self.
