Baba Srichand, the eldest son of Guru Nanak, had founded a religious sect of his own known as Udasis. He visited Amritsar and came to see Guru Ram Das. On seeing Guru’s long flowing beard, Baba Srichand asked him jocularly why he grew it that long. The Guru replied,To wipe the dust from the holy feet of the saints like you. ‘Your this sweet humility is the magic that makes you so great and makes me feel so small,’ replied Srichand. Baba Srichand promised the Guru his co-operation. After that the Udasis spared no pains to serve Sikh eligion. It is said that after the death of Banda Bahadur, when the Mughal rulers decided to root out Sikh religion, it was the Udasis who kept the Divine spark of the Sikh faith alight.
