What is method acting? There are so many definitions but which is the definitive?

The process of method acting has been defined by so many different people but I think Stanislavsky' term (Definition 1) for this is the best and easy to understand;

Definition (1): an acting technique introduced by Stanislavsky in which the actor recalls emotions or reactions from his or her own life and uses them to identify with the character being portrayed.

Definition (2): (Wikipedia Research below) Method acting is a phrase that loosely refers to a family of techniques by which actors try to create in themselves the thoughts and emotions of their characters in an effort to develop lifelike performances. It can be contrasted with more classical forms of acting, in which actors simulate thoughts and emotions through external means, such as vocal intonation or facial expression. Though not all Method actors use the same approach, the "method" in Method acting usually Wrefers to the practice, advocated by Lee Strasberg, by which actors draw upon their own emotions and memories in their portrayals, aided by a set of exercises and practices including sense memory and affective memory.

Method actors are often characterized as immersing themselves in their characters to the extent that they continue to portray them even offstage or off-camera for the duration of a project. However, this is a popular misconception. While some actors have employed this approach, it is generally not taught as part of the Method. Method acting has been described as "revolutionizing American theater." While classical acting instruction "had focused on developing external talents," the Method was "the first systematized training that also developed internal abilities (sensory, psychological, emotional)."[1] Method acting continues to evolve, with many contemporary acting teachers, schools, and colleges teaching an integrated approach that draws from several different schools of thought about acting.
