I have seen people telling others that the way they are using to connect to god is not right and there are better ways etc. Anyhow, I came across a story in the book, The Forty Rules of Love by Elif Shafak,which I absolutely loved. Here it is:
“Allow me to tell you a story.” And here is what he told us: One day Moses was walking in the mountains on his own when he saw a shepherd in the distance. The man was on his knees with his hands spread out to the sky, praying. Moses was delighted. But when he got closer, he was equally stunned to hear the shepherd’s prayer. “Oh, my beloved God, I love Thee more than Thou can know. I will do anything for Thee, just say the word. Even if Thou asked me to slaughter the fattest sheep in my flock in Thy name, I would do so without hesitation. Thou would roast it and put its tail fat in Thy rice to make it more tasty.” Moses inched toward the shepherd, listening attentively. “Afterward I would wash Thy feet and clean Thine ears and pick Thy lice for Thee. That is how much I love Thee.”

Moses immediately understood his mistake. The next day, early in the morning, he went back to the mountains to see the shepherd. He found him praying again, except this time he was praying in the way he had been instructed. In his determination to get the prayer right, he was stammering, bereft of the excitement and passion of his earlier prayer. Regretting what he had done to him, Moses patted the shepherd’s back and said: “My friend, I was wrong. Please forgive me. Keep praying in your own way. That is more precious in God’s eyes.” The shepherd was astonished to hear this, but even deeper was his relief. Nevertheless, he did not want to go back to his old prayers. Neither did he abide by the formal prayers that Moses had taught him. He had now found a new way of communicating with God. Though satisfied and blessed in his naïve devotion, he was now past that stage—beyond his sweet blasphemy.
“So you see, don’t judge the way other people connect to God,” concluded Shams. “To each his own way and his own prayer. God does not take us at our word. He looks deep into our hearts. It is not the ceremonies or rituals that make a difference, but whether our hearts are sufficiently pure or not.”
