Earth-touching Sign
It is also called touch the ground sign. Cover your right knee with your right hand, and touch your finger to the ground to show conquering the demons. According to legend, during the practice of Sakyamuni, he was constantly disturbed by the demon king to prevent the kiyonaga of Shakya. Later, Shakya touched the ground with his right finger to make the earth testify, so the god of the earth came out to prove that Shakya had become the Buddha, and finally the demon king was afraid.
