Today commemorates the day Buddha gained Enlightenment.
“Traditions vary on what happened. Some say Siddhartha made a great vow to Nirvana and Earth to find the root of suffering, or die trying. In other traditions, while meditating he was harassed and tempted by the god Mara (literally, “Destroyer” in Sanskrit), demon of illusion. Other traditions simply state that he entered deeper and deeper states of meditation, confronting the nature of the self.”
