Anupam Kher shared an emotional video, “Amit Ji, I wish you a very happy birthday. May God give you a long and healthy life. May you get all the happiness in the world. May your health always be good. You have given us so much happiness in our lives. You have taught us so many lessons in life without us realizing that you are doing it. In my personal life, in the beginning of my career, when I was told that it is very hot and you don't feel it, you told me that if I think about the heat, I feel it. If I don't think about it, I don't feel it. That initial lesson taught me in the next 40 years that patience is the most important factor in any profession”
