The goal of Buddhism whether Theravada or Mahayana is to end suffering. By doing so one ends rebirth or reincarnation.
Yet in Mahayana Buddhism the ideals of a the Bodhisattva is to delay one’s entry into Nirvana and return or reborn to help save all others.
In this sense Mahayana Buddhism is active and Theravada is passive.
As a Buddhist this is an important question. It is a question which ultimately will determine how you approach the way you live.
