Lieut. Sir Alexander Burnes, writer

In his book, Travels into Bokhara (1834), he writes that the fearlessness, calmness and boundless courage of the Sikhs crosses all the beliefs. They are the bravest among all the Indians. Sikhs are very open hearted. Rising above the hurdles of casteism, they behave with others with great love, pleasure and soft-heartedness.
With the virtues bestowed by the Guru, they raise the level of Sikhs in the eyes of the whole world.
