Māra Saṃyutta Māra throws a boulder
Thus have I heard, once, the Buddha was staying near Rājagaha on Gijjhakūṭa Mountain. The sky was covered with clouds. It rained lightly and lightning flashed brightly everywhere. At that time the World-honored One was walking in the open at night. There King Māra the Bad had this thought: “The renunciant Gotama is staying in Rājagaha on Gijjhakūṭa Mountain; the sky is covered with clouds, it is raining lightly, and lightning is flashing brightly everywhere. While he is walking in the open at night, I should go and disturb him.” Having thought thus, King Māra went up that mountain and pushed a large boulder down to hit the Buddha. The boulder however shattered by itself. At that time the World-honored One spoke a verse:
“You might destroy Gijjhakūṭa Mountain / turn it to dust; you might break apart / the vast continents and the immense ocean. However, to inspire fear / in someone who has attained true liberation, to make his hair stand on end / will never be possible.”
At that time King Māra thought: “The renunciant Gotama knows my thoughts.” He became depressed and dispirited, made his body invisible and returned to his heavenly palace.
