These practices are known as the six (transcendent) perfections, or the six paramitas. Some Buddhist teachings mention ten perfections in stead of six.
The six perfections are:
2. Ethical discipline
4. Joyous effort
The Six Perfections must be cultivated in order to become enlightened. Enlightenment is to become a buddha, an exalted being that has cut off the roots of ignorance and been released from cyclic existence.
By practicing the first four perfections one generates discipline and harmony in physical and
verbal actions. According to the law of karma positive actions are necessary means in order to cultivate the fifth perfection, concentration, and harmony and stability in the mind. The practice of the first five perfections is to use skillful means and accumulate merit. Without wisdom, the sixth perfection, one will not be able to develop a buddha's exalted understanding of reality
and therefore enlightenment is impossible.
The fourth, enthusiastic effort, is the indispensable support of all perfections.
