How are we to know a teacher, then? The sun requires no torch to make him visible, we need not light a candle in order to see him. When the sun rises, we instinctively become aware of the fact, and when a teacher of men comes to help us, the soul will instinctively know that truth has already begun to shine upon it. Truth stands on its own evidence, it does not require any other testimony to prove it true, it is self effulgent. It penetrates into the innermost corners of our nature, and in its presence the whole universe stands up and says, "This is truth." The teachers whose wisdom and truth shine like the light of the sun are the very greatest the world has known, and they are worshipped as God by the major portion of mankind. But we may get help from comparatively lesser ones also; only we ourselves do not possess intuition enough to judge properly of the man from whom we receive teaching and guidance; so there ought to be certain tests, certain conditions, for the teacher to satisfy, as there are also for the taught.


The conditions necessary for the taught are purity, a real thirst after knowledge, and perseverance. No impure soul can be really religious. Purity in thought, speech, and act is absolutely necessary for any one to be religious. As to the thirst after knowledge, it is an old law that we all get whatever we want. None of us can get anything other than what we fix our hearts upon. To pant for religion truly is a very difficult thing, not at all so easy as we generally imagine. Hearing religious talks or reading religious books is no proof yet of a real want felt in the heart; there must be a continuous struggle, a constant fight, an unremitting grappling with our lower nature, till the higher want is actually felt and the victory is achieved. It is not a question of one or two days, of years, or of lives; the struggle may have to go on for hundreds of lifetimes. The success sometimes may come immediately, but we must be ready to wait patiently even for what may look like an infinite length of time. The student who sets out with such a spirit of perseverance will surely find success and realisation at last.
