Yin–Yang Release

The techniques make simultaneous use of Yin Release and Yang Release. Yin relates to one's spiritual energy and Yang relates to one's physical energy and it's necessary to utilize both of these in order to mold chakra for ninjutsu.

The Sage of the Six Paths was able to use Yin-Yang Release to use Izanagi. He used Yin to make his dreams take form, and then used Yang to make his fantasies real, and could even make life. According to Madara Uchiha, the Sage used Izanagi to create the tailed beasts out of the chakra from the Ten-Tailed Beast.
