If we are able to survive, live in peace and free from disturbance, and follow and practice the Dharma well, we should be thankful to the many people who help and support us. That is why Buddhism teaches us to repay four types of kindnesses: the kindness of parents, the kindness of the Three Jewels, the kindness of one's country, and the kindness of other sentient beings. Some people also count the kindness of teachers.
