If you want to be an astronomer you must go to the observatory, take a telescope, study the stars and planets, and then you will become an astronomer. Each science must have its own methods. I could preach you thousands of sermons but they would not make you religious, until you first practiced the method. These are the truths of the sages of all countries, of all ages, men pure and unselfish, who had no motive but to do good to the world. They all declare that they have found some truth higher than that the senses can bring to us, and they challenge verification. They say to you, take up the method and practice honestly… So we must work faithfully, using the prescribed methods, and light will come.

Vivekananda (1863 – 1902)
