As pleasure and pain pass before his soul they have upon it different pictures, and the result of these combined impressions is what is called man’s ‘character’. If you take the character of any man, it really is but the aggregate of tendencies, the sum total of the bent of his mind; you will find that misery and happiness are equal factors in the formation of that character. Good and evil have an equal share in moulding character, and in some instances misery is a greater teacher than happiness.
In studying the great characters the world has produced, I dare say, in the vast majority of cases, it would be found that it was misery that taught more than happiness, it was poverty that taught more than wealth, it was blows that brought out their inner fire more than praise. (CW, 1:27)
Swami Vivekananda Thoughts on Meaning of Rishi
The Rishi is defined as a Mantra-drashta, a seer of thought; not that the thought was his own. Whenever you hear that a certain passage of the Vedas came from a certain Rishi, never think that he wrote it or created it out of his mind; he was the seer of the thought which already existed; it existed in the universe eternally. This sage was the discoverer; the Rishis were spiritual discoverers. (CW, 3.119)
