Sincerity

His Holiness Radhanath Swami Maharaj spoke in his Vyasa Puja - " If you are sincere in what you do, then Krishna will always help you". To illustrate this , he told about his own experience . When he was sitting on a rock in the Ganges, he was thinking if his heart was harder than the rock to cause such sadness in the hearts of people who have done so much for him and would always be by his side, his parents. But he believed, if you are sincerely doing something then God will help you. And many years later, he says, " Now my relation  with my parents and brothers is stronger than what it was before! This is truly Krishna's arrangement."
Whatever we do, if we do it with a willing heart, then we will truly achieve something just like hard work, if we work hard then success is assured. My mother also says , " No matter what you do, do it sincerely and with complete dedication , whether it is playing, studying, chanting, etc.
I would like to conclude by saying that whatever we do, we should do it with dedication, determination and sincerity and this will give us total satisfaction  "I have done my best!"
" A sincere soul is not trying to make a show. His enthusiasm is an act of service."-Radhanath Swami
