He was very deep into his meditation for months until his body radiating that made gods that reside on Kahyangan worried because Arjuna’s energy turned Condrodimuka crater exploded, thunder struck at noon, and even the mountain where Arjuna meditated lifted to the sky.
Batara Guru, the leader the gods sent Batara Narada to finish this matter as sending beautiful goddess, as usual, did not work to wake Arjuna up. Batara Narada went to the mountain where Arjuna meditate and asked him to quit meditating unless men and gods will be harmed by disaster. Arjuna did not quit, and he intended to get more attention from gods so they give him powerful weapon or supernatural power. Batara Narada returned to Kahyangan and reported his failure. Finally Batara Guru sent Batara Ismaya in the shape of Semar and Togog. They meditated at the same mountain as Arjuna, and with they power their body got taller and bigger than the mountain. They cut the mountain and threw the mountain away that at last made Arjuna quit meditating. Arjuna was advised by them, and that what he did was not correct. The mountain where Arjuna meditate is named Mt Arjuna, and the other cut is named Mt Wukir.
