You don’t get enlightenment, it gets you! Actually you “get” enlightenment, or it “gets” you, after you train your mind to be very focused, uncluttered, calm and still. When you can concentrate single-pointedly without distraction, you can focus on philosophical questions with enough power to understand deeply esoteric concepts. Without that training its as hard to reach enlightenment as it is for a couch potato to win a marathon. “Getting” enlightenment also requires cultivating a complete, utter compassion for all sentient beings. Various practices can help you to really understand and feel in your heart a loving-kindness for everyone: so much so that without question you always put the needs of every other sentient being before your own.
