Mara, "Lord of Desire" = Satan (In Buddhism)

As you study more about Buddha and Buddhism, you'll learn that Mara, the Lord of Desire attacks the Buddha many times in his journey but Buddha prevails.

Mara is afraid that if Buddha achieves ultimate knowledge and finds the solution to end suffering, he will end all Desire hence destroying Mara.  Especially the last night when Siddhartha is inches away from attaining his answer, Mara attacks him with EVERY pleasure that can be done.

However, Siddhartha remains unmoved and falls for nothing.

If you were to look at this with Christian eyes, it's basically as SATAN or the Anti-Christ was attacking Jesus over and over and Jesus prevailed and never fell for his trickery.  Just an interesting analogy to help you understand. It helped me understand.
