Pandit Jawaharlal Nehru wrote a birthday letter from Naini Prison to his daughter, Indira, on her 13th birthday. — Nehru tells his daughter to be transparent in all aspects of the liberation fight and to never do anything behind closed doors. — He instructs his daughter to labor in the sun and light. He says people will not follow you if you are not willing to sacrifice yourself for them. Nehru's letters were published in book form in 1957 under the title "The Selected Letters of Jawaharlal Nehru". Here is an excerpt from the letter: "You must realize that if you want to lead others, you must first lead yourself. People cannot follow your example if you do not give of yourself. Give of your energy, enthusiasm, and ideas, and they will be taken up by others. "Labor in the sunshine and the light. This is important. You must know that if you want others to work with you, you should also work with them. Help them to understand their duties and let them know what can be done efficiently by somebody else. It is not possible and it is very unhealthy. "Be honest and truthful in every matter, especially those that affect others. If you lie or cheat, even unconsciously, your reputation will be destroyed forever among people who matter to you."
