One day, when Vinoba's mother Rukmini Bai was busy cooking, he came there and put a roll of papers in the kitchen-fire to burn.
Mother - "Vinoba, what are you doing?"
Vinoba - "I am burning my school and college certificates."
Mother - "Why? They would be of use some day later in life. What harm is there in keeping them?"
Vinoba -" No. They are of no use to me. I shall never take any salaried job."
The certificates were all burnt down to ashes.
