Law of Causation

The interplay of the philosophical concepts in the Matrix story, is one of the best parts of the whole trilogy. Sample this (Matrix Reloaded)

Merovingian: But do you? You think you do but you do not. You are here because you were sent here, you were told to come here and you obeyed. [Laughs] It is, of course, the way of all things. You see, there is only one constant, one universal, it is the only real truth: causality. Action. Reaction. Cause and effect.
Morpheus: Everything begins with choice.

The Law of Causation is first discussed when Neo, Trinity and Morpheus visit Merovingian. He taunts them on the reason they have come to meet him.

According to Vedanta the phenomenon of the world is due to the play between Cause and Effect. The Law of Causation as described in Swami Parthasarathy's book has two heads : Law of Destiny and Law of Karma. The Law of Destiny connects one from their past to their current status. The Law of Karma deals with the past, present and the future.
