Whoever sets out to persuade men to accept a new idea, or one which seems to be new, not just as an idea, but as a truth that is felt, should know beforehand that the human mind is not a blank sheet, on which one an write with ease, and should not therefore grieve or despair when he finds that people do not pay attention to him.
Just as a tested and rugged virtue of the moral hero is worth more than the lovely, tender, untried innocence of the child, so is the massive strength of a soul that has conquered truth for itself worth more than the soft peach-bloom faith of a soul that takes truth on trust.
For truth there is no deadline.
Sentiment and principle are often mistaken for each other, though, in fact, they widely differ. Sentiment is the virtue of ideas; principle the virtue of action. Sentiment has its seat in the had; principle, in the heart. Sentiment suggest fine harangues and subtle distinctions; principle conceives just notions, and performs good actions in consequence of them. Sentiment refines away the simplicity of truth, and the plainness of piety; and "gives us virtue in words, and vice in deeds."
The simple truth is, that there has lived on the earth, “appearing at intervals,” for thousands of years among ordinary men, the first faint beginnings of another race; walking the earth and breathing the air with us, but at the same time walking another earth and breathing another air of which we know little or nothing, but which is, all the same, our spiritual life, as its absence would be our spiritual death. This new race is in act of being born from us, and in the near future it will occupy and possess the earth.
The wise man learns to meet the changing circumstances of life with an equitable spirit, being neither elated by success nor depressed by failure. Thus one realizes the truth of non-duality.
