Diligence is steadfast application, assiduousness and industry—the virtue of hard work. It is one of the seven heavenly virtues.
Diligent behavior is indicative of a work ethic — a belief that work is good in itself.
Diligence in Buddhism
The last words of the Buddha was "Strive on with diligence". Diligence is an integral part of all Buddhist teaching, and is considered the fourth of the pāramitā. In Mahayana tradition diligence is the third pāramitā and the first which is said to lead to liberation. The practice of diligence will bring an increase of qualities.
