Our teacher: Our inspiration “Teachers plant seeds of wisdom which grow forever.” An ideal teacher can not only give us the right knowledge, fill us with hope, give wings to our creativity and imagination but also help us to lead our lives well- a life based on the right values and virtues. It was after Anne Sullivan’s entry into Helen Keller’s life that it changed her life for good. Rising above the disability if Helen achieved all that she had, it was due to the support of her devoted and loving teacher.

Our former President Dr. A.P.J Abdul Kalam too attributes his success to the role played by his teacher, Iyadurai Solomon. He told him to desire and dream for something from the heart and assured him that if he did, his dreams would come true. And for Dr. A.P.J Abdul Kalam it did. Let us respect our teachers who play many roles in our lives. They selflessly impart knowledge, tell us the right from the wrong and mould us into great citizens and wonderful human beings. Aware of our strengths and weaknesses they guide us to our goals. It is rightly said: ‘A society cannot rise above its teachers’.
